I've got a chicken who's acting like she's sick. A couple of months ago she hatched a batch of eggs and has been fine since. She's always been a very healthy bird and had never acted sick in any way. However, i recently noticed that she wasn't walking around as much and she's started to kind of lay back on her elbows with her feet stretched out in front of her. She also now can't stand up very well and has a hard time keeping her balance. Oh and the other thing is that she's acting almost like their's something stuck in her throat but it feels normal and doesn't seem like something is stuck Does anyone know what this might be and what i could do to help her?
