Kudos to your wife! I'm curious . . . does it seem to most people that vets are more willing to give up on chickens? I'd certainly send the screw to the vet, just to say "nyah nyah," but don't hold your breath waiting for the money he stole (yes, I believe what he charged you was outright theft, especially considering he didn't actually do anything helpful).
Oh, and what kind of magnets did she used? Ever since reading this post, I'm terrified there may be some screws out there, waiting to lodge in my chickens.
