This is the first time I have had a chicken act like this and I have had chickens for almost six years now....she is about two years old maybe a little younger....she was laying eggs before not sure if she is now...she doesnt walk very fast and stays puffed up and does a lot of sitting...what on earth could be wrong with her? Egg bound? What should I do? She is eating, drinking, and pooping...her poop looks normal. I fed them some hard boiled duck eggs this weekend and she chowed down on them...not sure what to do...I really feel sorry for her!
