I have six six week old RIR pullets. I just finished their new coop which does not have a run. I was hoping to let them free range when they are older. For now we have been letting them out with close supervision. Yesterday our barn cat who is a very good hunter was hanging around the chicks. My wife and I were both keeping a close eye on her. At first she seemed uninterested in the chicks (she has been around them before.) Suddenly she took off like a shot after one chick. She ran about twenty feet straight and jumped over a row of sweet potato plants where she hit the side of my boot If we had not been there I have no doubt we would be down to five hens. Will the hens ever be safe around the cat?
