I have never had this happen to any of my chickens before, but Saturday, I noticed one of my bantam cochin hens was having a hard time trying to walk. When I examined her, she had a nasty gash on her right leg, just below the bend on the back side of the leg. Her other leg was a tiny bit irritated but ok, I guess it was from the way she was walking. I took her inside, washed the legs and poured some peroxide on the gash to try and get any debris out and then applied some bag balm to it. I didn't want to give her any antibiotics at the time since the wound did not look or smell infected, no swelling. That was the last day she has walked. I would guess she is about 5 years old (I got her and several others from a couple that didn't want to keep chickens anymore and were just going to let them fend for themselves, released in their woods, so they couldn't tell me how old the flock was). I have had her for 3 years. On Saturday, she looked otherwise healthy, no discharge and her vent area was clean, very alert. She ate very hearty on Saturday (I have had her in the house since then), ate ok on Sunday, but not as good as Saturday. Monday, she was shivering and when I went to pick her up that morning, she was really hot with fever but the wound still looked good, no swelling or redness or change in smell. I gave her a 1/4 cc injection of pen G, IM. She didn't want to eat much at all, but I was able to get a bit of yogurt in her and some water dripped onto her beak. I figured it was because of the fever, she wasn't hungry. Tuesday, she didn't feel as hot, almost normal, the pen G must have started to kick in. She has had injected antibiotics for 3 days now. I have to really try hard to get her to eat even a little bit. I have tried all her favorites just trying to get her to eat. She lays with her feet out in front of her and I have to prop her with a towel so she doesn't fall over. I am doing (physical therapy) on her legs, to keep them limber. She can curl her toes but she won't move either leg. The wound looks like it is healing, it's a bit smaller. I have no idea what happened to her or how long her leg was like that. I watch my flock every morning when I let them out, making sure nobody is picking on anyone and that everyone is acting normal. Sometimes I wish chickens weren't prey species and insist on hiding their pain until it gets bad! I feel like a lousy mom for not noticing sooner. I made her a sort of chair to help get her off her bottom and maybe get those legs working. Sorry if the quality isn't great, I took this with my cell phone this am.
