I have some chicks that I pulled from their mother and are raising indoors. I've done so in the past and haven't ever had this problem. They have started pecking at each others backs until they have big bleeding sores with no feathers. They started with just one yesterday and I doctored him up and set him free on the yard. Well when i got up this morning to put them in their outside pen to scratch and feed on grass, as I do daily, i noticed another victim. I doctored him as well and turned them all out thinking they may have been a bit crowded. I had to leave and when i got back four more have been pecked on to the point of bleeding. I am lost as to what i should do. They have free range now and get freshly ground feed and water daily. What more can I do? I am afraid they will eventually peck each other to death. Please help!!!!!
