This morning I went out to the coop to find the two EE's in with the two silkies. They were separated with two different rooms. We had a tarp covering the EE room. Eventually, we were going to put all four chickens together, but since this happened can I leave the EE's in with the silkies? By the way, they seemed to have established a pecking order and they are all hens.
I've had EEs in with my silkies for a while with no problems. I did have problems putting silkies in with a standard rooster. They really got abused. But I've never had any problems with hens once they have worked out the pecking order. Your EEs just wanted company!
