Ok.. so here is Lucy, whose comb over the past week and a half, has taken on a pinkish cast - as well as small waddles that have a pinkish cast. She is roughly 4 weeks old now. Nothing about her personality seems roo-ish to me, but then again - that white one (Mr. Bob) that you will see in a couple pics is pretty laid back, too, and he has a gigantic red comb for his young age (also 4 weeks). I'm really keeping my fingers crossed that Lucy is a she - I have no problem keeping ONE rooster, but I'd rather not have two. The only way I'd cull is if one is aggressive. On another note - do you think these chicks are too small to put in with my other chicks, who are about 8 weeks now? Right now I put them outside in a dog cage during the day. We have a dog and woodsy animals that would think they are a great snack. Thanks for your help!
