Woke up at 3 am a few nights ago to one of my chickens going crazy. I opened coop door and she ran out faster then usain bolt. Couldn't find her for a good half an hour but then found her stuffed between a fence and a tree. I grabbed her and she freaked out. She had ants all over her. So I washed her off and let her stay in the bathroom. While washing her off I found some injuries under her wing. I put hydrogen peroxide and neosporine on it. I introduced her back to the other hens and they've been treating her right. But since that first night, every night and about 1-3 am she goes Beserk unless I can find a secluded place for her to stay. Her leg is also turning black and blue and I'm not sure what to do anymore. She has three holes in her leg where the bleeding was coming from. Almost look like bite marks but idk. I'm attaching pictures. Any help is appreciated.
