Is there a book anyone can recommend for chicken genetics? I am increasingly interested in color genetics, and I need a book! LOL. I have 3 babies a broody bantam hatched out last month. They are about 7 weeks old and she's still taking care of them! Anyway, one of them, if I didn't know better, I would be sure he was 100% purebred Delaware! It's really amazing! My first chickens were Delawares, so I am familiar with what they should look like. He's all white with black tipped wings and perfectly flecked/barred neck and tail feathers! His legs are bright yellow. The only thing that's off is his comb looks like a single comb, but it's a little fatter than a normal single comb. He hatched out of a green egg! There is no Delaware in his background that I am aware of at all! Another one of the group that hatched out of a green egg started out mostly white, but is now looking more like mottled black, with white feathered legs! Neither parent had feathered legs! It's so funny! The other looks like my silver EE's, but it has a large red single comb. Here's a pic of them, about a week old, so their color has come in a little more since then: That's their mama off to the right, not in the picture. They are almost the same size as her now, but she still tries to cover them all up at night! Too cute!
