I went out a little while ago to make sure the chickens were getting ready to head to the coop for the night. All were fine. My EE Rooster decided to catch my 5 1/2 mo. old Tetra Tint pullet and mate with her on the concrete driveway. He stood on her for a few seconds afterwards. When she got up, she was limping pretty badly. I picked her up and checked her over, but couldn't tell where she was hurt. She sat in my lap while I rubbed her leg and then I sat her back down. She hopped to the coop and up the ladder to the top where she hunkered down for the night. My question is, where typically would an injury like that occur? Hip maybe? If she's still favoring it in the morning I'm going to isolate her so she doesn't get pinned to the ground again and injured more. I just don't know what to look for. Thanks in advance!
