I'm not sure if she's choking or it's something else, but one of our Red Star hens, Abby, keeps stretching out her neck and acting like she's trying really hard to swallow something. She's acting like she's going to throw up and is trying to hold it back. What's wrong with her? She just ate (layer pellets) and her crop is really full, maybe a bit too full than it needs to be. It's not red or swollen, it's just really hard and full of food because she just ate. Any thoughts? She's roosting right now with the rest of her flock. She isn't acting lethargic or anything. Her eyes are bright and normal, they aren't tired-looking. She looks fine except for how she's gulping, like she's going to vomit. Oh and she just recently started doing it a little while ago today, after she ate. Maybe did she eat too much? Thanks!
