I have been raising 8 chickens with the intent of giving half to my sister (she'll add the 4 I give her to her existing flock of hens). I want to be sure I keep 4 confirmed hens for myself, but I'm not sure on a couple. THEY WILL BE 8 WEEKS OLD IN A FEW DAYS. One in question is a slower developing Australorp who has taken much longer to develop all it's feathers. The other are the Barred Rocks....One developed a comb the second week & seemed to be pushy with the rest of the flock. Currently its comb doesn't seem too large & isn't yet red in color & the behavior has subsided. The other barred rock doesn't seem to have tail feathers & though there's no comb growing upright, the comb "area" seems wide & red (almost looks like it might be a pea comb, but I don't think that happens with Barred Rocks).....Any help is appreciated
