My three-year-old Delaware hen hasn't been doing well recently. I found her in the nesting box yesterday morning just standing there, not making any noise, which isn't at all normal. I isolated her from the others, and she either lays down or limps around a bit. She hasn't laid an egg, but I've seen her straining a little. She passed some whitish liquid a few times, and pooped last night. I'm worried the egg might have broken inside of her. If it has, is there anything I can do? She's like a pet, and I don't want to lose her.
