Our 2 RIR's (1 yr 5 month old; Foghorn & Leghorn) and our newbies--a BR & BO (almost 5 months; Betty & Wilma)--have been "integrated" in the coop for almost a month now, but we're still having issues. While there hasn't been any pecking that has brought blood or injury, the two RIR's chase the younger ones away from everything and try to get them off the roost at night. We free range them in the yard during most of the day and Betty & Wilma used to go into the coop early and get settled, but now one of the older ones goes in there and the younger girls seem to intimidated to even go in the coop. One night after it was dark, we found them hanging out on our deck (where they all spend too much time pooping anyway). Other times, we find the little girls end up sleeping in one of the nest boxes and boy do we hear it in the morning if Foghorn or Leghorn needs to lay an egg and Betty & Wilma are in the nest box! In the morning, while Foghorn & Leghorn will be out in the run before we come out, we often find Betty & Wilma still on the perch; they seem scared to come down while the older girls are still in the run/coop. Have any of you had trouble with small flock integration after a month? Will they every gel into one flock? They certainly have seem to have established their pecking order (poor Wilma is at the bottom and Foghorn is at the top), but mostly hang around the yard in "cliques" of two--older and younger. We've been managing and intervening when we find it necessary (like to move Wilma or Betty from the nest box to the perch once it's dark), but are about to take a trip for two weeks and I'm worried!! Our neighbors will be caring for the birds, but we want it to be as easy as possible for them. Betty and Wilma should start laying any day now and I don't know if there will be issues with the nest boxes or what will happen. Any advice or ideas would be welcome!
