Clarence Elliott was a British horticulturist. In 1927 he travelled to South American on an expedition to collect exotic plants and animals. On his return to England in 1928, a small group of light yellowy-brown, crested Chilean hens ( Araucanas ) that laid blue eggs was given to Prof. R.C. Punnett who was the director of the Cambridge University Breeding Program. Michael Pease worked alongside Punnett as a member of the program. The program’s aim was to create an auto sexing utility breed where male and female day old chicks could easily be sexed.
Punnett discovered the auto-sexing ability of chickens while studying different types of barring patterns in chickens. He learned that any pure breed with the sex-linked cuckoo barring on top of a brown variety bird would be auto-sexing.
In 1930, Clarence Elliott returned after a second expedition to Chile. He brought back 3 more Auracanas, which he gave to Punnett. One hen died but Punnett was able to cross breed with a Gold Penciled Hamburg Cockerel. The result was gold hen with irregular penciling.
Although, the auto-sexing feature was advantageous for the poultry industry, the birds were not very productive and in 1935, Punnett imported a Barred Plymouth Rock Hen from Canada and mated it with three Danish Brown Leghorns as the Danish line was more productive and hardier. They have cream plumage.
Meanwhile, Michael Pease had also created a Legbar with a cream plumage.
When Punnett, learned of Pease’s cream discovery they decided to see if the cream colour in the Legbars was the same gene in Punnett’s Creams. Tests proved they were both of the same gene.
The offspring resulting from the fusion of the two cream lines were selected for crests to distinguish them from Gold and Silver Legbars, blue egg laying ability, and clear markings of the auto-sexing feature. Punnett introduced these birds at the London Diary Show in 1957.
These were standardised in 1958 but nearly died out in the 1970s as there was no demand and it couldn’t compete with the modern commercial hybrid egg layer.
The breed was rescued by the Werniess Collection and David Applegarth.
