I have 9 1year old hens and a 6month old rooster that I am trying to merge with 8 3month old chicks. They have been in the same coop (but separated by chicken wire) since the chicks were just days old. The older birds usually free range all day but I have kept them in and opened the coop divider 2 days ago but they are still segregating themselves. They really don't pay each other much attention, but I can tell the younger ones are leary of the older birds. Any advice? I want to eventually let everyone out to free range, but I'm worried if I do it now, the young birds will be afraid to come back into the coop. Should I just give it more time, or are there any tricks I should know about? Thanks in advance!
