Pretty sure my Bantam Cochin is a roo... I was cleaning the brooder late last night (insomnia) and I noticed that his comb is starting to turn pink, all the other chicks from that age group are still orange (except the Silkie, black obviously) And I think that one of them tried to crow while I was in the bathroom this AM. Someone made a long strangled noise. The one month olds appear to be mostly feathered, pretty much everything except the very tops of their heads, which are coming in but not full yet. I'm possibly going to put them outside this afternoon, and if that goes well I would like to get them outside into the coop (if I can get the whole thing done this week)
