I think my hen has egg peritonitis. She has has been acting different for a couple of days. I have no avian vet where I live. Her symptoms are like egg bound but we felt no egg. She stands like a penguin with her tail down has hard abdomen and can feel her bones. We feel no egg. She ate some bread and yogurt and I gave her oyster shells. She did drink too. She poops too. I was wondering what I could give her. Her abdomen is hard and not too big. What could I giver her, does duramycin 10 work?-- some have had luck. Anything that has worked and can be purchased like at Tractor Supply would be helpful. Thank you so much!
