I'd like to know if it's a simple thing to breed for or a difficult one. I'd also like to know the basics about it. I have some green legged roosters and some pink legged hens. When I bred them together, some of the offspring got fabulous yellow legs. Some of them also have pink legs, but none of them have green legs. I'd like to have an explanation for this so I could produce the same result deliberately in future, as I really like the yellow legs! If anyone can take the time to give me a quick outline I'd be extremely grateful.
