I don't know how else to put it. My hen walks around standing straight up with her butt dragging the ground. She acts like her butt is hurting. I noticed that her eggs now have some wierd lines on them like there is something going on in the shell formation. She is getting weak now and the other hens are starting to hen-peck her. Should I isolate her for now? And do you think she will make it? Anyone know what is wrong with her. Thank you.
