I've had a series of deaths in my chicken flock and want to send the next one for a necropsy. I am suspecting Newcastle disease, as I mentioned in previous posts. I live in Mass., and our county extension office has been sluggish in responding, and reluctant to fund necropsies, even though another person in my same town had the same type of symptoms and deaths in her flock last fall (she called them last fall, and they refused to fund). I could take her to an avian vet on my own, but the only one around here doesn't see birds very often, and doesn't seem terribly knowledgeable. I want to have this done by someone whose findings I can trust. Is there someplace reliable to send a body? How do I have to prepare and send her? If it is a bird that I have to put down due to unending suffering, is there a particular method I need to use? Is chopping the head of okay? I prefer to do that because I know that death is as sudden as possible.
