Hi Everyone. Looking for advice or help with one on my ducks. She become very poor, no appetite, mostly just standing or lying. She is 1yo Indian Runner. I've check her all over and don't see anything wrong, her poo is yelowish-green and quite often she is lying down with her head and neck stretched in front on ground. Can obviously see she doesn't feel well. I gave her vitamins yesterday but not sure what else I could do. Vet said the only thing they do is euthanasia as they don't deal with poultry. Please please any advices will be very appreciated
