She was being held down so we could get the picture. She is very active, eating and drinking. The spot started very small and has continued to grow over a few months. The peck mark is new. We brought her in to clean it off. She is now separated.
This is a 1 year old brown leghorn hen. She is eating and drinking well. Very active and vocal. Started as a small bump and has turned to this. Any ideas what it is and what I should do for it. I have her separated to keep others from picking on her. Thanks in advance for your help.
