I had gotten 2 ten day old Ameraucana chicks back in November and kept them separated from my mixed flock of 6 six month old layers until a few weeks ago. When I introduced the chicks I placed their crate in the coop and kept them there for 2 weeks. I began to integrate them with the older girls when I was working in the coop in the evenings. There was some pecking from time to time and I would put the chicks away. When the 2 most aggressive hens left the chicks alone everything was fine. I began to leave the chicks in with the pullets overnight about 3 days ago. There was some pecking but nothing really aggressive. Well this morning I went into the coop to find one of the chicks pecked to death and the other absolutely beside herself. I separated her and brought her in the house. Now I am afraid to leave her with the others. What should I do? I need to integrate this now lonely chick into the flock. Any help would be appreciated.
