Thanks so much. I had to get to the vet clinic before noon. I had talked to the vet earlier, and he said to call with the dosage, and he would have someone get it ready. I found something online that suggested 1.6 cc liquid for a 13-pound goose. That's what I told the vet clinic person.
When I got there, there were 10 syringes loaded with a note that read, "This is a stronger Baytil, so .4 is right." Vet was otherwise engaged, so I didn't get to ask any questions. But, I still figured having it was better than not having anything until next week when the avian vet is reachable.
So, I'm hoping for the best.
