Egg and Prolapse combined

[CherriesBrood]

Help! Our new layer has an egg stuck inside the membrane sack hanging outside her body.

We've helped another prolapsed bird before, but never one with a full large egg in it still. We've tried to clean the area with warm water and gently push the egg back in, however she keeps pushing it out. The egg cannot get free of her sack. No vets available today to help us!

Have you tried soaking her in a warm water with Epsom salt?
Plain Epsom salt, not the "favored" kind.
