A couple of weeks ago I noticed one of my sapphire gem hens was puffing up its feathers. It was very cold out and it was cold out for days on top of getting a big snow storm so that’s why I thought she was just cold. We put a ton of bedding and straw in the henhouse at night to try to warm her up. I did notice that the other three sapphire gem hens we have were doing very well and not bothered by the cold at all. Then the weather got a little warmer and this specific hen’s feathers were still puffed up. We brought her in the house to warm her up. After being in the house for a day and night her feathers were still puffed up. I looked her over and saw a black scab on her foot which I suspect was bumble foot. At this time she was still eating and drinking water. We treated the bumble foot the best we could from what we saw online which was getting rid of the scab and cleaning it out and putting antibiotics on it. I also did the epsom salt before removing the scab. It looks like it’s healing well, it’s no longer black and does not look infected at all. We have been keeping her bedding clean and replacing her bandages daily. It’s been a week and she seems to have gotten worse. She is still puffed up and now not eating or drinking and she is very lethargic. I can get her to eat treats, like an egg, but she eats it very slow. She won’t eat her regular food, won’t drink the water I change every day, and won’t drink any Gatorade. There’s no swelling anywhere on her face and nothing coming out of her eyes or nose. From what I could see, her butt looks clean. Last night she was very lethargic and I didn’t even think she was going to make it through the night. I woke up today and she was still alive, standing up and then laying back down after. Still not drinking. We are getting a syringe today to try to get some water in her. I just don’t know what’s wrong and if there is anything else I should be doing or treating her for?
