Aylesbury

The Aylesbury is a heavy domestic duck developed in England and named for the town of Aylesbury in Buckinghamshire. It is one of the best known white ducks in the world, recognized by its pure white plumage, a horizontal body carried low to the ground, and a long pinkish-white bill that sets it apart from most other white breeds.

For much of the nineteenth and early twentieth centuries the Aylesbury was the standard market duck in Britain, raised in large numbers for the London trade. It was bred for size, fast growth, and pale flesh and skin rather than for egg laying. Mature drakes commonly reach around 4.5 to 5 kg and ducks around 4 to 4.5 kg.

The breed is calm and gentle by nature, with low energy compared with lighter ducks. It is heavier and less inclined to fly, which makes it manageable in a yard or small farm. Purebred Aylesburys are now uncommon and the breed is considered rare in its original form, with many birds sold as Aylesburys being white commercial crosses.

Who it suits

The Aylesbury suits keepers who want a calm, ground-based duck and have enough space for a heavy bird that needs clean water and shelter. Its docile nature makes it a reasonable choice for families and for people new to duck raising, as long as they understand it is a meat-type breed and not a high-volume egg layer. Anyone interested in conserving traditional poultry breeds may find value in keeping purebred stock, which is harder to come by than white commercial hybrids.

White ducks have been raised in the Vale of Aylesbury in Buckinghamshire since at least the eighteenth century. Cottagers in the area kept ducks in their homes and yards and supplied the growing London market, sending birds to the city by road and later by rail. The trade was centered in the town's Walton district, which became closely associated with duck raising.

Through the early nineteenth century breeders selected for size, a pale bill, and white flesh and skin, qualities valued by London buyers. The local water and soil were sometimes credited with the bird's pink bill color, though selective breeding was the main factor. By the middle of the century the Aylesbury was established as a distinct breed and dominated the British duck trade.

The Aylesbury was among the breeds shown when organized poultry exhibitions began in Britain in the mid nineteenth century, and a breed standard was set to describe the ideal type. Show birds were bred toward a deep, low, boat-shaped body and a very pale bill, which gradually separated exhibition lines from the working market ducks.

From the late nineteenth century the Aylesbury faced competition from the imported Pekin duck, which grew quickly and bred well. Many keepers crossed Aylesburys with Pekins or moved to Pekin-based commercial stock, and pure Aylesbury numbers fell. Both World Wars and changing farming patterns reduced traditional duck keeping further.

Today the purebred Aylesbury is rare. Conservation-minded breeders maintain small numbers, while the great majority of white table ducks sold under the Aylesbury name are commercial white hybrids rather than the original breed.

The Aylesbury is built long, broad, and deep, with a body held nearly horizontal and a keel that can almost touch the ground in well-bred exhibition birds. The plumage is pure white throughout. The most distinctive feature is the bill, which is long and straight and a pale pinkish-white to flesh color, unlike the orange or yellow bills of most other white ducks. The legs and feet are orange.

Coat and colors

Aylesburys come in white only. The feathers should be clean white with no yellow or cream tinge, which is one reason keepers value clean bathing water and dry bedding. Drakes and ducks look alike apart from size and the drake's curled tail feathers, so birds are often sexed by voice: the duck has a loud quack while the drake makes a quieter, raspier sound. Ducklings hatch with pale yellow down before growing into white adult plumage.

The Aylesbury has a quiet, even temper. It is friendly toward keepers it knows and rarely aggressive, and its heavy build means it spends most of its time walking and foraging rather than flying or running. Around the home flock it is sociable and settles well in a mixed group of ducks. With strangers it tends to be cautious rather than nervous, and birds handled regularly from a young age become tame and easy to manage.

With other animals the Aylesbury is generally peaceful, though like any duck it can be stressed or hurt by dogs and cats that chase it. Drakes are usually milder than those of lighter, more active breeds. The ducks are not especially noisy day to day, but a duck will quack clearly when alarmed. Their low energy makes them less of an escape risk than flighty breeds, since they cannot fly over normal fencing.

Aylesburys are low-maintenance compared with many fowl but their size and white feathers create a few specific needs. They are not built for cold, wet, muddy ground and do best with dry footing and access to clean bathing water.

Grooming

• Provide clean bathing water deep enough for the duck to dip its head and spread water over its back, which keeps the white plumage clean and the eyes and nostrils clear.
• Check the bill and eyes for grit and discharge, since the pale bill shows staining easily.
• Inspect feet and legs regularly for cuts or signs of bumblefoot, a common problem in heavy ducks on hard or dirty ground.
• During the annual molt expect a period of feather loss; keep bedding clean to protect new feathers.

Exercise

• Allow daily ranging on grass to forage for plants, slugs, and insects.
• Keep paths and gates flat, as heavy ducks tire and can strain legs on slopes or steps.
• Avoid driving or rushing the birds, which can cause leg injury in a large breed.

Environment

House Aylesburys in a dry, draft-free, predator-proof shelter at night with clean bedding such as straw or wood shavings. Give shade in hot weather, since heavy white ducks tolerate heat poorly, and keep the ground well drained to reduce muddy, soiled plumage and foot problems. In the Philippine climate, shade and constant fresh water are critical throughout the year.

Feed a complete pelleted ration formulated for ducks or waterfowl where available; standard poultry feed can be used if it is not medicated with additives unsafe for ducks. Always provide constant clean drinking water alongside food, because ducks need water to swallow and to clear their bills and nostrils. Offer insoluble grit so birds can grind food, and a separate source of soluble calcium such as crushed oyster shell for laying ducks.

Treats and supplements

Suitable treats include leafy greens, peas, chopped vegetables, mealworms, and small amounts of grain such as wheat, all given in moderation so they do not replace the balanced ration. Niacin (vitamin B3) is important for growing ducklings, so a waterfowl feed or a niacin supplement helps prevent leg weakness. Floating greens or grain on water encourages natural foraging behavior.

The Aylesbury is a sturdy duck when kept on dry, clean ground with good food and water. Most health problems in the breed relate to its weight and white plumage rather than to inherited disease. With good management an Aylesbury can live 8 to 12 years, though heavy ducks bred for fast growth may have shorter working lives.

Preventive care

• Keep housing dry, clean, and well ventilated, and change bedding regularly.
• Provide clean drinking and bathing water at all times.
• Maintain soft, well-drained footing to prevent foot injury.
• Feed a balanced ration with enough niacin and calcium for the life stage.
• Watch weight and avoid overfeeding rich scraps.

Aylesburys are kept on the ground and cannot fly over normal fencing, so housing focuses on shelter, drainage, and protection from predators rather than on height. A yard, paddock, or small farm with grass and a pond or large water container suits them well. They need somewhere dry to rest by day and a closed house at night, since ducks left out are easy prey for predators.

Setup checklist

• A predator-proof house with solid walls and a secure latching door.
• Dry, deep bedding refreshed regularly.
• Drinking water and separate bathing water, both kept clean.
• Shade from trees or a shelter for hot days.
• Well-drained, flat ground to limit mud and foot problems.
• Low fencing or netting to keep ducks in and ground predators out.

Aylesbury eggs take about 28 days to hatch, the standard period for most domestic ducks. Eggs can be set under a broody duck or hen, or incubated artificially. Many heavy table breeds are unreliable sitters, so incubators are often used for Aylesburys. Duck eggs need higher humidity than chicken eggs and benefit from daily cooling and light misting from the second week, which mimics a sitting duck leaving the nest and returning with wet feathers.

Hatching steps

1. Collect clean eggs and store them pointed end down at cool room temperature for no more than about a week before setting.
2. Warm the incubator to a stable temperature and humidity before adding eggs.
3. Turn the eggs several times a day and candle around day 7 and day 14 to check development.
4. Cool and lightly mist the eggs once daily from the second week.
5. Stop turning and raise humidity around day 25 for lockdown.
6. Leave hatched ducklings in the incubator until they are dry and fluffed before moving them to a warm brooder.
