My hen was acting classically eggbound (puffed up, tail down). She is only about 24 weeks and laid her first egg a couple days ago. I soaked her in epsom salts and warm water, and the egg popped out, but covered by membrane. I could not find an opening in the membrane at all. The egg is hard and fully formed. I gently pushed it back in. When I tried to soak her again, it came out again, so I did the same thing. She is resting now in a dog crate inside. Has eaten a few bites of yogurt with Tums and olive oil. Should there be an opening I am looking for? When I feel it inside her, it is behind the left wall of her vent.
