I have a hen who has literally just been standing still for at least 24 hours. A couple of days ago,I noticed she seemed slightly lethargic and wasn't running around with the other chickens. she seemed to improve, then yesterday she pretty much just started standing in one place. My first thought was that she is egg-bound,so I started giving her sitz-baths with epsom salts and gentle massages. I can't feel an egg,but I know that doesn't mean there isn't one. She isn't eating or drinking. Her comb and eyes are bright and she's looking around with seeming interest,but she's just not moving,even to sit down. Anyone have any idea what could be going on with her?
