If you can give them a separate pen, it should be more peaceful.
I've completely separated them away from the girls. They're in a converted stable now and I'm in the process of building them a run next to it. I built the ply box inside the stable but I don't think I'm going to need it. They crowed at the top of their lungs this morning and I didn't hear a thing until I went outside and visited them. They seem a bit depressed being away from the girls, but I'm sure they'll forget about it in a few days. They've managed to avoid the cutting block with the move, so a couple of days of moping is better than being dinner.
There's absolutely nothing special about them or their breed: they're a dime-a-dozen; but we hand raised them in our first flock, so it's nice to have some roo's getting along so well and watching their shenanigans. They love people and they're way more interesting than the girls!
