About a week ago, my hen was attacked by something unknown and left a hole on her back. (We have no roosters). Ever since, she won't let me pick her up and if I come to pick her up, she comes at me sideways putting her head down and shuffling. I've have her since she was a day old and always held her. She used to come running to me like a puppy, she knows her name and loved to be held and I would carry her around the yard. Now she won't even come up to me. Any ideas?
