Would love some input on the way we are going about integrating our two groups of chicks. One group is nine chicks, 11-17 weeks old. The other group is fourteen chicks, 7-9 weeks old. The oldest two are Orpingtons and the youngest three are Silkies, so as you can imagine there is quite a big size difference, and the Silkies will never catch up. I've read a few integration articles and posts on here, and it seems like it's better not to intervene unless there is actually blood shedding, but I don't want them to stress each other out either. The oldest group went out in the coop first. About two weeks ago we started putting the younger group in the run in a separate area during the day. Last week we put the younger group in the coop in their own area. Now when the older ones are out free ranging, I let the younger ones in the run. Both groups have access to water, but the older ones don't have feed when they're free ranging. I keep an eye on them, and when it looks like the older ones want to come back for feed, originally I was just blocking the younger one's access to the coop temporarily and letting the older ones in. The past few days, I was letting one or two of the older birds in with the younger ones. This went mostly surprisingly well, with a bit of chasing and pecking and noise but mostly nothing serious. One or two of the big ones still don't seem to like the younger ones at all though. Yesterday, the older ones were wanting in to the run/coop, so I let them all in together. One of the older ones (Luna, a Brahma) immediately took it upon herself to chase and peck at the babies, but the rest ignored them and went straight into the coop to eat a bit. Luna eventually stopped chasing little ones and went in to eat too. One of the younger ones (a RIR roo) hopped in with them, and I immediately went around to watch them in the coop as I was worried about the one little roo in with the nine big ones. Surprisingly, they completely left him alone. In fact, he was sitting eating food and pushed his way in front of Luna and I didn't see any guarding or pecking on the part of the bigger ones. He finished up first and went back out. Once the bigger ones were all done eating though, they all went out in the run and started chasing the babies around. Again, I didn't see any really serious pecking, besides Luna was a bit rough, but it was constant, non-stop chasing of the babies, and I ended up shooing the bigger ones out so the babies could have some peace. So the question is, am I moving too fast? Should I not be letting the older ones have access to the babies at all yet? Or, on the flip side, am I intervening too much? Should I just stand back and let them chase each other around as long as there's no real feather picking going on rather than shooing the bigger ones out again after they've eaten? I'm considering potentially locking just Luna up by herself in the baby's part eventually, since she is one of the only ones who seems to be particularly aggressive towards them, but would that be really stressful for her? We're gone for an entire day in a week and a half, and so I won't be letting the older ones free range that day. I would like them to either be completely integrated before then so I don't have to worry about them killing each other, or I'll just leave the babies in their separate area inside the coop and just let the older ones into the run while we're gone that day. They would be fine, I've had to leave the babies inside a couple of times due to heavy rain and they don't fight at all in their little area (though oddly, they do do a lot of chasing and chest bumping in the run, where you would think they should get along better because they have so much more room!). Thank you, as always!!
