I noticed yesterday my hen was trying to lay an egg without success, and shes still not able to lay it today. Just earlier she had a small part of it hanging out, and she also tried pooping/laying. Poop did come out, but the egg part was still there. So I grabbed some gloves and gently tried helping her. I managed to pull a small chunck off but then she sucked the rest back in. Any advice or help on what do to now?
