I have a pullet who is hanging off to the side, is standing still and eyes keep closing like she is falling asleep. Unusual behaviour for her I noticed right away. I then went to collect the eggs and one was layed outside the nest box, a large thin unusual shell, with half the shell missing. I suspect that the two are connected. What should I be watching for? I put her in a dog crate with some water and she seems content to just sit there for now
