The Legbar is a rare British auto-sexing breed of craven. Information technology was created in the early twentieth century by Reginald Crundall Punnett and Michael Pease at the Genetical Institute of Cambridge University.[6] They cross-bred American barred Plymouth Stone birds with brown Leghorns and created the gilded and silver colour varieties. Pease created a foam Legbar past cross-breeding these with white Leghorns; afterward crossing with Araucanas caused this to have a crest and to lay blue or bluish-green eggs.[7] : sixty
History [edit]
The Legbar was the second car-sexing chicken breed created by Reginald Crundall Punnett and Michael Pease at the Genetical Institute of Cambridge University, later the Cambar, which was created in 1929 by crossing barred Plymouth Rock with gilded Campine birds.[6] [8] [9]
The Legbar arose from cantankerous-breeding of Plymouth Stone birds with brown Leghorns, which at that time were ii of the main egg-laying breeds. As with the Cambar, they set out to breed a bird that would both have brown downward and carry the barred gene (B), and then that chicks would have sexual activity-linked plumage differences that could easily be distinguished.[vii] : 53 [six] : 317 Standards for the gold and silverish colour varieties were drawn up in 1945 and 1951 respectively.[10]
The cream Legbar was created past chance. Through cross-breeding of gold Legbars with white Leghorn stock, Pease had obtained some foam-coloured birds; their eggs were white, and they had no crest. An experimental crossing of these with some cream-coloured Araucanas from Punnett'due south laboratory led to the creation of the cream Legbar, a crested layer of coloured eggs for which a standard was fatigued up in 1958.[7] : 53 [four] [xi] : 193 Within a curt time it became very rare, just has since recovered.[4] It is treated by the Poultry Society of Great United kingdom of great britain and northern ireland as a colour variety of the Legbar,[vii] : 53 but is considered past the Rare Breed Survival Trust to be a separate brood.[4] Both the Legbar and the Foam Legbar are listed among the UK breeds on the watchlist of the trust; neither is considered "priority".[12]
Characteristics [edit]
A seven-week-old cream pullet
The Legbar has three colour varieties: aureate, silverish and foam. The cream variant has a crest and lays bluish, olive or green eggs.[9] The Legbar is considered a rare breed past the Poultry Club of Great U.k. and, until the Autosexing Breeds Clan was re-formed, fell under the Rare Poultry Society.[7] : 60 [13]
Use [edit]
The Legbar was bred as a auto-sexing layer brood. Hens may give 180 eggs or more than per yr.[10]
