I have two Welsummer roosters about 2 1/2 months old. I had a sub-cage for a ~5 week old Penasendesca chick within the same coop. Thank goodness I came home early. One of the Welsummer roosters must have flown from the roost into the cage. He pecked the heck out of the poor chick. The chick was hiding under the light fixture. Opinions? Should I kill the rooster before he is abusive again? I moved the chick into the house. None of the other 5 Welsummers or two Marans (one is a rooster) have been attacked.
