My hen Hermione Raven has been sitting on the egg box for two hours, panting, and she won't drink water. She's gasping and fluffing herself up, and she's taking so long that I'm worried she's egg bound. I can feel the egg inside her. Should I give her an Epsom salts bath? I don't know if I should because I don't want to stress her out more, so maybe I should just wait longer to see if she will pass it? What should I do?? Thanks in advance!
