Are they a breed or what ? I have seen lots of pics of them. Are they just a genetic experiement or what ? If anyone knows let me know i have a bet with a friend and she ows be a few copper marans chicks if i am right and there not a breed. Edit : Found more info. Here's part of a report from the World Poultry magazine: 'In 1954, the American researchers Abbott and Asmundson found several featherless mutants among New Hampshire chicks that hatched at the University of California at Davis. The mutation, named Scaleless, has been bred and maintained since then in Davis and in several other research institutions. The Scaleless line, like its New Hampshire origin, is, according to Prof. Cahaner a good egg-producer but with a small body and not much of a meal. Prof. Cahaner started 12 years ago to pursue his interest in the naked neck and frizzle genes that reduce the feather coverage of chickens, and a few years ago he came across the idea of using the scaleless mutant to breed a completely featherless broiler. In an interview with World Poultry, he said that the idea was to backcross the small scaleless chickens into a large, fast-growing broiler line in order to develop, featherless broiler chickens which grow as fast as the commercial feathered-covered broilers that reached the marketing weight of 2-2,5 kg in just six weeks. He noted that intensive breeding of fast-growing broilers started some 60 years ago. Twenty years ago broilers reached the marketing weight at about 9 weeks. Today, broilers reach that stage after six weeks, which has an enormous economic advantage. The featherless broilers created by Prof. Cahaner have apparently been bred using conventional crosses between scaleless chickens and commercial broilers, followed by backcrossing and selective breeding. We did not employ any genetic engineering procedures in breeding the featherless broiler. The skin of the naked chicken is a normal skin, but with no feather follicles and no subcutaneous fat, Cahaner noted. The Israeli geneticist added that in the late 1970s, featherless broilers were bred and evaluated at the University of Connecticut but, he explained, these broilers did not grow as fast as commercial broilers do today and for them overheating had not yet emerged as a serious problem, hence they were not considered useful at that time, as he was quoted in The New York Times."
