I have 5 32 week old hens...they all got along great...today i saw to going at it...I went out to break it up and there was blood on their combs..one worse than the other..I put flour on the cuts to stop the bleeding and hopefully the others wont start pecking...i put 1 in the coop and closed the door...but in about 1/2 hour they will all b ready to go in for the night...will they b ok in the coop...will this continue or could it be a one time thing?
