Ponds

Pond Location

The ideal site for a collection of wildfowl is probably a fairly extensive garden with natural running water. Waterfowl enjoy basking in the sunshine, but appreciate shelter from strong winds. Because ducks in particular spend a lot of time on the water, a sunny and sheltered position for their pond is favoured.

Where waterfowl are concerned, the more water the better!

Ideally, a pond should not be sited under trees where falling leaves can sink and accumulate, as they will rot. Leaves that do fall should be removed by skimming before they sink. Willow is very attractive, it comes in many forms, but sadly there are problems associated with willow leaves: Cladosporum spp. of mould that lives on willow trees can affect feather quality.

If a pond can also be seen from one of your windows then all the better. The word ‘paddlinge’ is a medieval collective noun and describes a pool on which ducks, presumably domestic, were kept to help calm the life of the keeper. Our distant forbears surely recognised the therapeutic quality of waterfowl on a pond, viewed from their living space.

Natural Ponds

A pond is usually preferable to a river or a stream so that water levels can be maintained.  An ’off-stream impoundment’ can be made by diverting some water and returning it further downstream. Before interfering with a natural watercourse, or even pumping, it is advisable to consult the local Environmental Agency Office, as there are regulations in force concerning water abstraction and related activities. The water level flowing out of a pond, possibly between a series of ponds, can be controlled by the use of a ‘monk’; a construction which is used mainly on fish farms since it enables the water level to be lowered relatively easily. The water normally falls over the top of the monk and is led away through an outlet pipe either to a lower pond or a series of ponds. Removal of the front boards leads to rapid lowering of the water level when pond maintenance or dredging is required, or if fish are to be caught! Where there is a neglected existing pond it should be dredged as deeply as possible for diving ducks, with shallower areas for the dabblers. A natural pond does not require any lining, but it is frequently desirable to protect the edges from erosion since the feet and constantly probing bills of wildfowl can be very destructive.

With a little work, a natural pond edge can look very attractive

Rough concrete, or carefully laid stones can form a permanent protection to banks, but all crevices should be sealed. Ducks in particular have a dangerous and sometimes fatal habit of dabbling in holes and cracks and getting their heads wedged so that they drown or are strangled.

Soft edges will need protecting. Heavyweight black nylon mesh (Nicospan or similar) could be staked alongside the banks as a protective barrier. In theory, vegetation grows through this revetment so that it becomes disguised, but in practice any leaves are frequently eaten or mutilated as soon as they appear. However, it is possible to plant more substantial overhanging shrubs which droop and form a camouflage. Even hardy plants with woody stems are likely to require protection from inquisitive bills in the early stages of growth. Secure them with a circle of hard netting whilst they get established.

Artificial Ponds

If natural water is not available, satisfactory small ponds can be of fibreglass (GRP) or concrete or lined with butyl. GRP is relatively expensive and is generally only readily available in very small sizes. It can be formed on-site though as a custom installation.

Concrete is renowned for its permanence so long as it is thick enough – at least 4 inches is recommended. If possible, the base should be laid a few days before the sides, and the joins should be rendered watertight with a proprietary bonding or sealing compound. Rearing pools can be constructed out of concrete blocks and waterproofed using swimming pool products.

Pond liners are an area where you usually get what you pay for. Top of the range is heaviest gauge of butyl. Thought should always be given to how birds will get out of the pond, even if water levels drop a bit for any reason. Edges of the liner will be constantly scratched by sharp claws. It will also degrade in sunlight if exposed. An overhanging edge of paving slabs not only screens the top of the butyl from the human eye, but it also protects it from damage as the waterfowl scramble ashore. There are black underlays available which can be used to hide edges, with time some grasses may grow into them if your stocking density is not too high. A properly installed and cared for liner should have a life expectancy of at least ten years, often more with butyl.

A butyl liner is expensive, but will last many years

Where any liner is installed, a flat protected surface at the lowest point is worth designing in. Mechanical pumps are heavy and generally need to remain upright when in operation. Consider how you will get them in and out of the water, and how you will provide power.

Water Maintenance

The greater the depth of an artificial pond, the easier the maintenance, because sediment settles to the bottom. This sediment is only disturbed if divers are present. On the other hand, when you do empty it out the job is a much bigger one. The water must be kept clean so that the birds’ plumage stays in good order and so that the eye and nose of the keeper are not offended. A soak-away can readily be incorporated in a concrete pond: if a pipe, of at least 75 cm in diameter, with a threaded end is placed through the lowest point of the base, the cap can be unscrewed and the entire contents allowed to drain away. The removal of the cap can be an unpleasant chore but with a little practice it can be achieved without the operator’s arm being immersed in a black, smelly and sometimes cold, solution for too long a period. Thereafter, vigorous agitation with a broom should ensure that the solid particles disappear down the pipe, along with the liquid. The more enterprising entrepreneur will install a release mechanism which can be operated from above water level. A vertical tube projecting a few inches above the level of the water is ideal.

Small ponds can be emptied by bailing out with a bucket. This can be quite a strenuous exercise if an appreciable amount of water is involved. Siphoning can be done but this is usually too slow a process and semi-solids get left behind. Pumping is therefore most practical but care must be taken to ensure that sediment does not block the mechanism. Agitation will mix the solids with the liquid so that the pump can cope. A sewage pump designed to cope with such solids does the job well, and the black muck can be pumped straight onto nearby grass. The smell dissipates after a few days and the turf will recover and appreciate the feed.

Waterfowl are at risk when a newly emptied pond is refilled. This is usually a slow process. The birds will want to return to the water as soon as they can. If the sides of the pond are steep, they will have difficulty in getting ashore until the water has returned to its natural level. The once-happy swimmers may wish to leave the water whilst the level is still low and during their frantic attempts to escape, they may become exhausted and perish. A temporary fence, erected around the pond until it has refilled, will avoid potential disaster. A raft in the pond, on which the birds can perch, will provide refuge until dry land is again accessible.

Anything floating may appeal

Rafts and Islands

Rafts and islands can be interesting and welcome features on all but the smallest ponds. Boards, say one inch thick, can be secured together with battens to form a floating island which serves as an admirable roost.

Buoyancy can be maintained by the fixing of partially filled plastic containers on the underside so that they are hidden from view. If the buoyancy is adjusted so the water overlaps the surface from time to time, for example when several ducks are roosting simultaneously, their weight lowers the raft and droppings are washed off.

A well-designed island is a tremendous asset for a collection of wildfowl in captivity. The banks on islands need to be protected even more than the shoreline, as you will not have such easy access for maintenance. Whether left natural or judiciously landscaped, the birds will benefit from the seclusion and relative safety from certain predators that the vegetation and comparative isolation will provide. The birds can be encouraged to nest on an island by the provision of nest boxes and by allowing undergrowth to flourish, but if eggs are to be collected, accessibility must be borne in mind.

It is a myth that waterfowl are safe from foxes and rats when on islands. Rats are particularly good swimmers and the vixen will stop at nothing if she has cubs to feed. Read our page on Fencing.

Aviaries

One method of keeping wildfowl on a small scale is to house one or two pairs in an aviary. Mandarin, Carolinas and several species of teal such as Ringed and Hottentot appear to adapt fairly readily to such confinement and an advantage is that they can be free-winged. The addition of small cage-birds can work as they don’t interfere with the ducks but careful choices on species need to be made. It is very important not to over-stock an aviary.

An aviary pool which is a metre in diameter and 30 cm deep should be adequate for one pair of ducks. If it takes the form of a concrete-lined depression, the water can be swept out almost daily without too much effort. The surrounding area must be previous and topped with loose small stones, such as pebbles, so that the water can drain away. Ducks love to pick up and play with small pebbles around the pond. Some pebbles will be dropped into the water so care must be taken if emptying the pond through a drain in the base. It is advisable to have a cage over the plughole to stop birds being sucked away.

Shrubs can be planted in the aviary to provide some privacy. Check that your choice of plants doesn’t include anything poisonous, there’s a basic list of poisonous plants in the sidebar. Artificial boxes for cavity nesters are essential if breeding is contemplated. Aviary birds are safer from predators than when in an open enclosure and within such a sheltered environment breeding results are often very good. Choose your species with care. If birds do not settle in reasonably quickly and show signs of distress, perhaps you should consider swapping them with someone who has more space and keeping something more suitable yourself. Please read about our rights and responsibilities (also in the sidebar) as waterfowl keepers.

The principles of biosecurity are frequently discussed, particularly in respect of the now possible threat of Avian Influenza.  Biosecurity is essentially the creation of a microbiological barrier to prevent contact between the pathogens (in this case Avian Influenza Virus) and the host (domestic or captive waterfowl).

The purpose of this note, therefore, is to consider aspects of biosecurity which can be put into place to protect these populations of waterfowl. Every waterfowl keeper will have a different set-up and it is possible to adapt their situation to fit in with these guidelines.

We should understand both the nature of the virus and the circumstances under which the virus can be introduced to our livestock.  There are two main ways the virus might be introduced. Firstly there is the risk of direct spread from migrating birds and secondly the indirect spread from these or another infected population.

Migrating waterfowl will be attracted to stretches of water and in the case of geese associated grazing.

The safest approach is to bring all susceptible livestock indoors and to keep them so confined for the length of the risk period.  Should this not be possible, then birds should be fenced well away from their swimming water if this is fed from a watercourse.  Efforts should then be made to avoid wild birds visiting the livestock.

An extra safeguard is to supply the feed and water inside the bird housing. Outside large water troughs must be avoided.

Having penned the birds away from water, it is an additional precaution if those pens can be netted over to prevent wild bird access. Your birds could be allowed access to a mains fed pond if it can be included in the netted area.

The virus is spread from the wild birds through the faeces. These will contaminate the edges of the ponds as well as the pond water itself and also any grazed pasture.  The precautions taken must consider how these faeces might get walked into the livestock pens.

  • Avoid walking round the ponds.
  • Do not go fishing, when clothes, footwear, vehicle and fishing equipment could become contaminated.
  • Change footwear before entering livestock pens (do not rely on foot dips).
  • Do not let dogs or other pets enter the livestock pens.
  • Always ensure the water provided to the birds is clean mains water
  • Drain or fill in any puddles.

Whilst migrating waterfowl may not visit your ponds they may be visited, for example, by local Mallard which could have picked up the virus from other ponds.

The other precautions to have in place are to avoid direct or indirect contact with other domestic waterfowl (or poultry) collections.

  • Do not borrow equipment from others.
  • Do not lend equipment to others.
  • Do not let other people visit your waterfowl.
  • Any staff must not have their own livestock nor have contact with other people’s livestock.
  • Do not visit other people’s livestock.
  • Do not bring other birds into your livestock pens (purchases, borrowings, gifts etc)
  • Do not take your birds to shows, exhibitions, etc nor bring birds from these events.
  • Do not lend your birds to anyone (eg a drake for mating other people’s hens)
  • Do not share a feed delivery with anyone.
  • Ensure stocks of feed are kept undercover in a clean, dry, rodent-free store.
  • Collect up and discard any spilled feed.
  • Don’t share incubation facilities with others.

Whilst this might not be a comprehensive list of precautions, it is sufficient to stimulate thoughts on the precautions to take.

If in doubt about anything, don’t do it.

The time to introduce these precautions is now. Don’t wait for the infection to be diagnosed in the country. Yours could be the first infected premises.  Register all livestock, however small the population, with DEFRA, who can then be expected to keep you informed of any increased risk of disease and keep you supplied with advisory notes.

If serious disease is seen in your birds, notify your veterinary adviser and DEFRA immediately. Remember, however, avian influenza in waterfowl may not make them sick.  This is why you must be suspicious of any other stock which is not yours and appears healthy.

Please follow this advice as closely as possible.

We recommend you locate a veterinary practice which has a partner specialising in avian medicine. This should be done as a basic part of planning your facilities. Some farm practices might be able to help, recommendation from other waterfowl keepers can be invaluable.

Birds mask their symptoms well as defence against being targeted by a predator. With careful observation we can detect a problem developing.

Sick birds often sit hunched up with fluffed out feathers. They may lose appetite, or simply hide away.

The topics and advice on these pages are given in good faith. The intent is to provide a general overview but is not a replacement for specialist veterinary care. If you suspect any of the following, immediate veterinary assistance is recommended:

  • Poisoning
  • Broken bones (especially if bone has broken the skin)
  • Attack by other animal
  • Swallowing something sharp
  • Significant wounds
  • Difficulty breathing
  • Eye injury
  • Prolapse (phallus or oviduct) that cannot be replaced
  • A need for pain relief

In the UK we face few restrictions as to which species of waterfowl we can keep. Only the (North American) Ruddy Duck is prohibited. This is to protect the endangered White-headed Duck.

As long as you keep them contained, that means not released or allowed to escape, you may keep all the other Anseriformes. All may be traded freely as long as they are individulally proven as captive bred. This means close ringed or microchipped for identification. Our native and ordinarily resident birds listed in Appendix 2 of the General Licence may be moved without a ring. Mute Swan and Egyptian Goose require an individual licence to be moved.

Our responsibility to these birds is to keep them in conditions sympathetic to a contented mental state. They should be adequately fed and watered, kept in comfortable conditions with relation to their size and normal habits, and sheltered from weather extremes. We should protect them from pain, injury and disease and allow them the freedom to express normal behaviour. We should do all in our power to protect them from fear and distress.

Essentially, these are summed up in the five freedoms of animal welfare. Expanded; four physical or functional domains of nutrition, environment, health and behaviour surround and influence the mental state. The Five Domains are key to the highest standards of welfare.

As the British Waterfowl Association we believe that the highest standard of welfare should remain one of our core values.

The clue is in the name – waterfowl. So the answer is yes.

The pond need not be huge for basic health, provided the water is changed frequently and kept clean. All waterfowl need to be able to fully immerse their heads in water, to keep eyes and nostrils clear. They nearly always wish to drink when feeding.

Clean water is also vital for bathing. Waterfowl know their survival is dependent on keeping their feathers in good condition, so a high proportion of their time is spent on washing and preening. They will have a regular routine of splash bathing, flapping, then rearranging their feathers.

Small bodies of stagnant water, especially in warm weather, can harbour disease. Waterfowl soil the water every time they bathe, so any disease or parasites present can be shared quickly amongst the flock.

Nearly all waterfowl prefer to mate on water. Particularly, the heavier breeds of domestic geese may be injured if forced to mate on land.

Geese and many of the ducks have evolved to eat grass – lot of grass. In the wild they range widely, mowing as they go. The intake of a goose is about 1/5 of that of your average sheep. Why eat so much? The answer lies in nutritional content. This varies according to the growth stage of the plant and also the season. All but the very freshest leaves are high in fibre and low in meaningful nutrition. No surprise then that newly emerged leaves are nibbled away with relish. Many people keep geese to manage grass and reduce the need to mow. There are merits in this strategy but only to reduce, not eliminate mowing. If the grass is bowling green short all summer, it will disappear completely over the winter.

Domestic ducks and geese are not always good parents, it very much depends on the breed.

Many breeders of domestic and wild waterfowl use small broody hens and have excellent results. Muscovy ducks are also used.

Wildfowl may reliably sit on a clutch. It will depend on the species as to how reliable they are if there is any disturbance in the vicinity. Some species are very secretive, like the Garganey. Others, like Eiders, will sit faithfully through all manner of civil unrest.

You will need to make a choice as to whether to lift the eggs early or leave the eggs under the mother.

There is a vast array of incubators on the market. Whichever one you choose, it is best to hatch in a separate hatcher. The bacterial contamination of hatching birds will affect any eggs of different stages still in the incubator.

Waterfowl are naturally inquisitive and will uproot and nibble any plants in and around the pond. Some native and common garden species are poisonous. We suggest that these should be avoided in a waterfowl enclosure where they could be nibbled:

  • Black (deadly) nightshade
  • Bracken
  • Bryony
  • Castor Bean
  • Clematis
  • Common St John’s Wort
  • Corn Cockle
  • Daffodil bulbs
  • Daphne berries
  • Delphinium
  • Some Ferns
  • Foxglove
  • Some Fungi
  • Hemlock
  • Henbane
  • Hyacinth bulbs
  • Hydrangea
  • Most ornamental Irises
  • Laburnum seeds
  • Lily of the Valley
  • Meadow buttercup
  • Oleander
  • Potato sprouts
  • Privet
  • Ragwort
  • Rapeseed
  • Rhododendron
  • Rhubarb leaves
  • Sweet pea
  • Tulip
  • Vetch
  • Yew
