When I checked on my Cornsnake this morning at about 10:30, she had laid three eggs, and there was a fourth right above her cloaca. I quickly covered her back up again, so as to not disturb her egg-laying, but noted that she didn't look well, and seemed like she'd been having trouble getting that egg out.
I left her alone for the next four hours, and checked on her again, expecting her to be done laying. Well, she still only had those three eggs, and the fourth looked in exactly the same position as before. She also looks very thin and weak, which is troubling because she's always been a great eater.
I don't know how long she'd been trying to lay that egg before I noticed. It may have been as much as 12 hours. But it looked like she wasn't going to get it out on her own, so I attemtped to manually remove it; I've had success massaging eggs out of another Corn before. But unfortunately it's not coming out, though I did get it much closer to her cloaca. I put her back into the eggbox, and left her alone again; hopefully my efforts were enough to help her get it out on her own. In the meantime, I had a friend call up a vet to see about Oxy injections. I know it's probably still a bit early for that, but I thought it's best to see a vet about it.
How long do you suggest I leave her alone before taking further action?
