I have some 11-12 week old chicks that I recently integrated into my flock. My husband and kids brought home 6 bantams (mixed) and 2 standard (EE and barred rock) as day olds. They were all in the brooder together without any issues and transitioned out to my second coop without any issues either. I just integrated them into my main coop about 2 weeks ago with the big girls and now they’ve started having issues. (Have not had any issues with the big girls. The littles have plenty of places to get away from them and they all free range). The issue is between the silkie cockerel (one of the littles) and the EE and barred rock littles. He’s a bit of a turd anyway, but he’s only causing issues with those 2. I’m assuming it’s because they are the only ones, other than the big girls (that he runs from) that are the same size/slightly bigger than him. They are both super submissive and have clearly given him the go-ahead to be at the top of their sub-pecking order, but he keeps running them away from their little flock. Everyone free ranges all day and I have multiple feeders and waterers available, so no issue there. I feel bad that those 2 are pretty much left on their own. I’m sure they’ll eventually join the big girls when they’re older. The real issue is happening at night. The littles have a crate inside the coop that they all sleep in so they can get away from the big girls. The last 3 days, the silkie will not allow the EE or barred rock into the crate. They end up cramming themselves next to the crate, against the wall of the coop. I have plenty of room inside the coop so I added a second crate for those 2, but they won’t use it. They prefer to sleep next to the other crate and wall. I’m assuming they want to be close to the others like they’ve always been?? I just don’t get what the issue is with this cockerel. I’m tempted to put the 2 back into the other coop (it has a shared run so they’d still be able to see each other) but I don’t think they’d be happy there and I don’t want to make the integration harder down the road. What do you think??? No one is injured and I’m not concerned about any potential injuries. He’s really just forcing them out. I just don’t get why he’s all of a sudden doing this. He’s fine with all the bantams.
