I came home to a chicken with blood on her comb. Some was relatively fresh, some had started to scab. It's hard to tell if she ripped it or if she hit her head hard on something. She has some crusted blood around her nostrils. There are splatters of blood on the feeder. I watched them for a long time and the other ladies are leaving her wound alone, thankfully! She is acting totally normal. What should I do at this point? Is there a cream I should put on it to prevent infection or should I let it be? I will continue to make sure no one pecks at her , and remove her if they do....anything else I should consider? Sorry for the picture quality...I had to use my cell.
