My hen had an egg that burst inside her today. She is really swollen and the other hens picked off all feathers around her vent. She is pushing with all her might and moaning/squealing. I put her in a warm bath and massaged her. I was able to pull out part of an egg shell. She is bleeding some. But I think she has pushed out some of her sack or intestines. Each time I try to push it back in, she pushes. Need HELP!
