Most vets will not see chickens, but you could call around. I would check with your state vet's office, and ask for details. Each state is different--some like California will do it free if you take the bird in. You could also call them about testing, then cull them yourself and burn the bodies or deeply buried them. One person recently was told by the state vet to say that they thought their chickens might have bird flu (avian influenza), and the culling and necropsy would be done pronto for free.
