I have a hen who has been sneezing for a while. She now has drainage from her eyes, even after treating their water with unfiltered acv. As much as I DON'T want to, I think it's time to cull this little bird. So how do you cull, especially inside city limits. I'm suburban and not quite legal. Can a vet put the bird down? Dh's aunt is a vet and though she doesn't work with birds, we may be able to get her to do us a favor. If not, how do I go about it?
