On August 3rd, one of my hens was acting weird and was messy, so I brought her in and we discovered an egg had broke inside. Some of the shell was hanging out. I gently pulled out what I could, which was a lot of shell. She immedietly started acting like herself. This past week she has not been looking so good. A messy butt, floppy comb, and she seems off balance. She still eats, drinks, and walks around with the rest of the chickens. We brought her in today and cleaned her up. She has watery brown diarhea and her bottom is swollen and firm. I don't know if maybe she got an infection from the broken egg or if she's now egg bound. Any advice would be appreciated. There are no vets around that are willing to treat chickens. I called 15+ vets when a different chicken was sick. The thought around here is that you put them down and get another when one gets sick.
