After returning home from an overnight trip, I checked my laying box and found one normal egg and one GROSSLY abnormal egg. Now one of my hens is lethargic and has her eyes closed. As you can see from the egg, it had a soft, rubbery shell, and inside it almost looked, and not to be gross, smelled like cooked chicken. She did lay a normal egg today and her vent looks okay, but she is very lethargic and not eating. Back in July she was attacked by a raccoon and pulled through that. She just started laying again about a week ago. Please Help!
