My drake Bella is prone to mild upper respiratory infections in fall/winter, and like clock work has started sneezing again this year about a week ago. No other symptoms, no drainage, just a sneeze. My other ducks are perfectly fine. When I noticed he was still sneezing this morning I called our vet. She recommended putting him on Aureomycin like we did last year. Now it worked great last year, and I was glad for it, but I HATE to medicate. And if I medicate him, that means the whole flock goes on it, and we don't get to have any of our hens yummy eggs. I keep a bag handy, just in case, so it wouldn't be a big deal to measure it out for a weeks supply and give it to them. But with only a sneeze I hesitate! What do you guys think? Treat them or hold off?
