So yesterday, one of my hens started acting a bit lethargic. She seems weak, but she's eating and drinking. She's walking a bit slow and laying in random places. I gave her some extra calcium and an epsom salt soak for fifteen minutes. I put her in a crate with some pine shavings. Her poop is a bit runny. I felt the sides of her vent and I don't feel an egg. Her abdomen feels a bit swollen...any suggestions or ideas??? I've never had an egg bound hen so I'm not sure if that's the problem.
