Well I am not much better, and having roosters look so much different than the hens is confusing too.It is called Know Your Chickens by Jack Byard.
But it really is for folk like me who struggle with understanding even the basics. It has been a long running joke on this thread that I barely know what a breed is (vs a color). They are all chickens to me - meaning I see them as individuals not breeds.
Thanks.
