Please help! I have tried introducing my 8 week old chickens to the 5 week old chickens (different breeds some) because the 5 week old's are nearly killing the 3 week olds, in fact they did peck one to death. I did give more protein to ALL chickens(grains/pellets/grasses/table scraps) which they all devoured and seperated the bigger from the smaller. Some of the 3 week olds are getting feathers again. So I put 5 week olds in with 8 week olds and they ran to corner to hide. I watched for a whild no serious problems. Later today I went out to see most of them pecked BAD and one in shock with tail missing. What can I do? They can all see each other through the wire/doors, I do not want to cull some of them, or free range as I am building a bigger coop just now. I really NEED ADVICE FROM SOMEONE as I do not know what else to do..... standing by and waiting for a reply. Thanke everyone.
