I think I know this is egg yolk peritonitis and she is bad, but guess I need to hear opinions. She has been this way for months. She gets listless and stops eating and I give her antibiotics which perks her up again but the swelling is now so bad she can barely walk. I've treated her 3 times with antibiotics. She actually laid a couple eggs after the first treatment but none since. She never did lay a lot of eggs. She still eats and drinks and has small but normal droppings. I am down to my last 2 chickens. At her age how much can she take? She is a feisty girl. Could it be anything else that could be cured? Thank you
