A good vet who is willing to look up info on chickens, even if they do not know much about them, is still invaluable. They have access to medications (pain meds, antibiotics, antiparasite) you cannot buy from the feed store or on line. They also have anesthesia equipment, sterile tools, and they have experience handling tissues. I think a vet who is willing to see your pet, and is willing to do some research on your behalf, is not a waste of money. They do this all the time (look things up), and this is NOT a bad thing. A vet who knows little about a specific species, is still a vet, who has a trained mind & hands, and has access to a vast online and book library. The more you encourage your vet to learn about chickens in general, the more helpful they will be down the road. I see people complain all the time on this forum that they cannot find a local vet to help them- If you have found one who is willing to touch the bird, and is humble enough to admit they do not know everything- and is willing to look it up! great! encourage them with your patronage (at least if you liked the person, even if you were disappointed by their lack of upfront expertise). This hospital would at least be a good place to have fecals run... round worm eggs and coccidia look very similar under a microscope across species.
