I've found remains of 3 eggs in the nest boxes and one on the floor. I did get 3 new layers from a friend of mine and integrated them. Everyone seems to get along, I haven't seen much agression. They all just avoid each other and I check on them CONSTANTLY to make sure all is well in the coo. I had taken the golf balls out since it seemed everyone knew what to do in the nest boxes, so I put them back in with extra shavings. They have a big bowl of crushed oyster that I mix a little scratch in with. 2 large feeders and one large waterer inside and a smaller one in the run. I'm pretty sure it's the new ones doing it because it just started when I put them in there. Any suggestions? I've heard to just cull them but I would like to try to break them of it first for a few days.
