A couple of misc questions.... Does anyone know of a vet in the Medina Ohio area that handles the care of chickens? We want to seal up a couple of small spaces in our coop to make sure there are no drafts. Does anyone know if "GreatStuff" will harm the birds? That's provided, the birds can fit into the spaces and want to peck at the insulation. Is it ok to use a heat lamp at night to keep the chickens warm? I ask because I don't know if the light will bother them while they sleep. Thanks!
