I was wondering when is a good time to put my 7 chicks in with my adults? I have two roosters and 6 hens now. Some are still pullets and havent laid yet some are already laying. The chicks are about 3 months old or so. They are BLRW chicks and adults. Right now they are in a brooder box in the coop with them. I would like them to get out of the brooder for more excersize.
