Just pulled a hen out of the nest box who had a portion of super thin egg shell (felt like stiff paper) hanging out of her vent. I pulled on it gently and out it came along with the egg white. When I picked her up out of the box, she pushed the yolk out. I just brought her inside and cleaned up her rear end (there was a large pile of feces she was sitting in in the nest box and it was all over her feathers). She's soaking in some warm water at the moment and seems to enjoy it. I'm not sure if all of the egg shell came out - should I be worried? Is there anything I should do to see if there's still a bit of shell in there? The warm water seems to have stimulated peristalsis as a small chunk of shell made its way into the bath tub at some point. Do I just wait things out and see what happens? I'm a relatively new chicken owner (almost a year) and I've not had this happen before. Any suggestions would be appreciated!
