Last week a dog got into my backyard and was caught dragging one of my 5 chickens - she was stopped and the chicken was rescued but by the time I got to her the wounds already smelt, putrid infection had set in. I cleaned her (so I thought) and treated the nasty wound I found not knowing there was another even deeper just out of sight. I found that 2 days later and it was awful, black skin and seeping slime. Lovely. More hydrogen peroxide and triple anti-biotic cream! Anyway she's doing ok for the time being, the skin looks healthy enough and the wounds are starting to scab over and she's eating drinking and pooping happily, she's even laying eggs. I'm sort of on top of this one homework wise although very new to doctoring chickens. I noticed another that looks like she's growing all new feathers and complains heavily when I pick her up. I brought her inside to see if she was injured by the dog also, but now I'm thinking she's going through a molt? The timing seems all off though it's winter too cold for her to do that. I don't know really what is going on with her yet but she's loving her indoor vacation. 3 chickens left outside and tonight I went to close them in and one had a yolk and a white streaming from her vent. I know she has already laid a perfect egg today and I was wondering if maybe it was one of those stress events causing her to expel an immature egg - changes in the flock, dog attack, and the cold temps we've been having, and I shut them in rather later than normal... She's only been laying about 4 months. I really don't want to have a broken shell inside, I guess I'll bring her in also for observation. Advice is greatly appreciated this is overwhelming! Should I bring the other 2 inside for visiting hours, or will they do something to get themselves admitted? My birds are Red Sussex and I can take pictures if you'd like. Thanks, Christine.
