In around mid to late March one of my one and a half year old Delaware hens got very sick, as she stopped eating and drinking, and she wouldn't like to move around. At first I thought she was egg bound and gave her the proper treatments but that did nothing, and I felt no egg in her. After a few days of giving her immune boosting foods, she seemed to have gotten much better, and would eat, drink, and move around like she did before. Although she still didn't lay any eggs. As time went on, while she still walked around and ate, and drank regularly her abdomen would begin to look slightly more swollen, and she would constantly go to sleep anywhere showing signs of weakness. In the past couple of days she has also gotten a noticeably bad waddle with her legs spread out, and now lays down anywhere, usually where she can hear us. I think she is internally laying because when she lays down she makes her broody sounds, and pumps her tail as though she were straining. Her poops at first were liquid with little dark green pellets, but now they look like regular poops although smaller and with more calcium in them. Is there any way to help her?
