My black sex linked hen Delia (she will be 3 in April) was diagnosed today with egg yolk peritonitis, poor thing. She stopped eating yesterday and I noticed she was sitting off by herself. Last year she had an impacted egg shell (which she expressed) and a resulting infection, so I thought this was happening again. Took her to my excellent avian vet who drained the fluid in her abdomen. Delia is staying at the vet overnight so they can get some fluids and food in her and start her on antibiotics. I will be giving her antibiotics and tube feedings when she comes home. They want to stabilize her for exploratory surgery to see if the egg yolk is contained to specific areas, of if it's all over the place. They said that sometimes this condition can be managed, where folks just bring their hens in periodically to have the fluid in their peritoneal cavity drained. But if the yolk is all over the place, there is no cure. Just wondering if anyone has managed this condition before.
