Today, I went to feed my hen Betty Jo and something is wrong. I'm thinking maybe someone fed her something because her coop and run are next to the privacy fence and it would probably be easy for someone just to throw something over it. She's very lethargic, I had to force her to drink water and I got her to eat something. She has cuts on her crown and she has green coming from where she lays. She was fine yesterday and I'm very worried about her. I put some antibiotic cream on the cuts and I do keep penicillin around in case one of the animals get sick. Should I give her a shot of that? If so how much, I've never given it to her before. Adding some pics.
