I recently acquired a Standard Bred flock of Buff Catalanas. The issue I'm having is that the "best" rooster in all respects has white shanks, they should be blue/green. I have two cockerels coming up with the correct shank color, but their trueness to type remains to be seen. Does anyone know the pattern of inheritance for shank color? If I use the white-shank roo, will he only throw white legs? His type is so good in all other regards. He was recently evaluated by Rev. Roland Romig (the original importer of the breed to the US) and in one breath I was told he was the best rooster I had, and in another breath I was told to cull any white-legged Catalanas. So, now I am at a loss. Any advice is much appreciated. To my knowledge, this flock is one of only two listed with The Livestock Conservancy and I am working on increasing their numbers. Thanks!
