Hi, all, I got all my chicks at TSC and some are two weeks old today (GSL, Cuckoo Marans, one bantam Cochin) vs some that are probably 4 weeks based on their feathers (4 Frizzle bantam Cochins, one Welsummer or Phoenix or something that looked like a chipmunk). I am basing the age of 4 weeks on this: wings fully feathered, shoulders coming in, breasts about 1/2 feathers, tails coming along nicely. Everyone gets along fine, no pecking, etc., and I guess that's from no one "owning" the brooder when I got them, since some people say they have problems with mixed age chicks, from my readings on this board. My question is: since they have been integrated in the brooder since day 1, what will happen if I take the older chicks out to the coop to live before the younger chicks? Will they lose their flock bond from the brooder? If so, I would then have to reintroduce the younger chicks when they move out. Can anyone give me some advice, please? Thanks in advance!
