I'm late getting to this thread I know...

But if it were me I'd print out the post by Corey AND rush off to the vet with the printed post in hand. That way you are covered either way and if the vet opts to go the route Corey suggests then you have a vet doing the proceedures and not yourself.

"You are going to jab the female through the belly directly into the stuck egg and drain as much liquid as possible" doesn't sound like something I would want to tackle. Corey's adept to it I'm sure...I'm not.
