I have 23, 9 week olds that I have had in the coop for about a month now and I have 16, 5 week olds that are still in the brooder that I want to put to the coop. Is it too early to integrate the younger with the older? I have a corner of the coop separated with walls of osb, so it's 4' tall. I was thinking it would be fine until I found some of the older ones perching on top of the wall, and the other day there were a few inside of the corner area. Do you think the older ones would leave them alone for awhile?
