Any experienced chicken-raisers - I have 3 white chickens, 2 black and white chickens, and 1 black chicken, all about 7 weeks old. Now I know that this is a ridiculously broad question, but any idea's of the breeds? IT"S JUST FOR FUN! All the breeds you suggest I'll plug in and see if I can find matching pictures! They're all from McMurray hatchery, "rainbow layers". Thanks!
