I have a brooder big enough for the chicks while they are small but when they get older they probably won't fit all in the same brooder would it be fine if I seperated them for a while then put them back in the same coop
The only problem I could for see by doing so is disrupting the pecking order that they are already establishing. You separate them into groups for a while and then when you put them all back together in the coop there might be a little more squabbling than there normally would be.
