2nd year hatching off chicks, 1st year went good. This year one of the hens is a chick from last year, the other hen is the same main mom from last year. Ok so there both sitting on about 23 eggs, they started hatching off and around 5 days old I noticed one was dead in the run area. I watched them for a while and eventually saw the bad hen simply pecked the face of one the chicks and then chased it and kept pecking it's face and once it was injured severely, she stopped and walked off with the rest of chicks following. I tried to mend the hurt chick but it passed away. I looked at the other chick that was already dead and the same thing was wrong with it, it's little eye and side of it's face was pecked except worse. I looked up inside the nesting box because I heard a new one up there and I knew it should've been down walking around by that point and I looked it there, it was still alive but a tiny single peck hole was near it's eye. That would did not make it either. This hens dad is a red shoulder Yokohama and it's mom is a silkie. I have no clue what to do except take her out and let my good main mom raise them. Any advice?????????
