My golden Australorp had sour crop. Took her to the Vet. They drained 30 ml from her crop. The Vet bill was $250. They sent fungal medicine home with me. She was doing better when I brought her home. I gave her the medicine before bed and in the morning. 6 hours later, she was dead. Can Vets really save chickens or should I just let it run it's course the next time I have a sick chicken? I really had high hopes that the Vet was going to save her. She was only 9 months old. I'm wondering if all of my chickens fall under DNR (do not resuscitate).
