Egg yolk peritonitis.... can a hen be cured?

[luisrosa411]

I am curious if anybody has heard of a hen being cured from egg yolk peritonitis. My vet told me it's almost always fatal. We have a hen we are treating with antibiotics, and her behavior and appetite have improved drastically, and the swelling in her abdomen is decreased. So, we are very hopeful. However, the vet also said she may have internal damage from the infection, so may not be able to begin laying again. So if that's true, I'm wondering if we are on a vicious cycle we can't get out of with her....?

Has anyone heard of a hen being cured from peritonitis to the point they begin laying eggs with proper shells again?

Thanks.

What antibiotic was used?
