What We Do Watchlist Ducks watchlist Aylesbury Key Characteristics The Aylesbury is not an easy bird to breed – relatively few eggs are laid and fertility is often lower than for other breeds, because the keel of the drake can interfere with mating. There have been times in recent years where numbers of this breed have been very low, but a concerted campaign to Save the Aylesbury and efforts to publicise and spread the breed have meant that there is a reasonable number of keepers at present. The exhibition Aylesbury has a carriage which is horizontal, the keel parallel to and touching the ground when the bird is standing at rest. The head is strong and powerful, with eyes near the top of the skull. The flesh-pink bill should be long, broad and wedge-shaped. The body is long and broad and the keel is very deep. The Aylesbury is a very heavy duck with the drakes weighing 4.5-5.4kg (10-12lbs) and the ducks weighing 4.1-5.0kg (9-11lbs). History The breed derives its name from the town of Aylesbury in Buckinghamshire, where it was bred as a white table duck in the eighteenth century and was used in increasingly large numbers to supply the London market. The white plumage was valued for quilt filling and the pale skin resulted in an attractive carcass. This light colouration is evident in the pink bill colour that continues to be a key characteristic of the breed. The Victorian emphasis on size led to the development of the modern Aylesbury with its pronounced keel and long, pink bill. It was standardized in 1865. Uses A heavy breed, Aylesburys make good meat birds and their pale skins results in an attractive carcass. Aylesburys lay between 40-100 good sized blue eggs a year, depending on the strain. Did you know? The public perception of an Aylesbury duck is rather different from the show standard. To the layman, any white duck is an Aylesbury, even if it has a yellow bill. This means the breed is actually much rarer than many imagine. Breed Societies For more information visit the British Waterfowl Association.
