So my blue cochin roo is sneezing, rattling, and sounds congested, similar to me with a respritory infection. I picked up some Sulmet and Terramycin, basicly to just have on hand. Any recommendation on which I should start him on? Sounds like people have used both for similar symptoms. I don't have a vet around that knows anything about chickens. I'm also going to give him some of the VetRx, which sounds pretty much like Vics for chickens.
