Where can I buy meds for my chickens? I have one hen who is wheezing. Several posts recommend using Sulmet or VetRX or polyvisol etc. I asked my regular vet and he pretty much laughed at me and said he did not know anything about chickens. And what about supliments? What are the brand names and where do I purchase them? I sure don't want to lose my flock. Thanks for the help.
