I have isolated my chicken. She had a problem with I believe egg laying. She was lethargic so I gave her a soak in the tub. She laid a egg that night that was weird it had almost like a paper shell around the egg. The egg inside looked normal. She has not laid today and she acts normal but dony want to add back to flock if still having issues I found a egg like this a week or 2 ago . What do I need to do differently or should add back to flock. Is drinking and pooping. Weird color like almost greenish color
