Good for you! As long as it was someone that knows geese guiding you. Everything is dosed for chickens and turkeys and waterfowl drink so much more water that it's really easy to overdose them. They're pretty sensitive to many antibiotics that chickens and turkeys can use, too. I've had the best luck with oxytetracycline myself. They seem to tolerate that pretty well. I learned the hard way last year not to use Tiamulin/Denagard on geese. The ducks did just fine, but even with probiotics, it killed all their gut flora and they were in agony. There just wasn't any research available on that on on waterfowl. My state poultry vet and I were working on that one together, too. Just FYI for the future. My birds weren't even clinically ill, just something wasn't right and I knew it. Whatever it was was very mild. I didn't lose any until the Tiamulin fiasco, and then, mercifully, only two.
