Yesterday one of my laying pullets was breathing very hard and struggling to lay an egg this morning there was no egg she has her tail down and is very droopy I think she's egg bound please help what can I do to help her we're going to soak her in some Epsom salt water and I'm giving her some oyster shell in a little bit of mashed but she doesn't want to eat it she's just standing there with her wings and tail all drooping and her eyes closed
