Last night I put my 4 chicks in the coop for the 3rd day and when I woke up to let them out 2 were dead on the ground, they had been pecked to death by my bigger chickens and the other two were hiding in a corner. I rushed in to get the babies and the chickens went for the smaller of the two survivors, I managed to catch her before any really bad damage was done but there was no saving the other two, they were to far gone . One was mine and the other one was my little brothers. I brought the 2 live chicks in the house and back into the brooder. I didn't know what else to do. They are two months old and are getting to big to be in the house. I had to tell my brother that a snake got to them but I feel so bad, my sisters chick (one of the survivors) was stumbling a little bit but seems good now. Is there anything I should watch for? They just want to sit on my lap and I think that's because I saved thier life. Can someone explain why my chickens did this? Can someone tell me how to stop it from happening again?
