I gave my rooster amoxycillin liquid orally using a small syringe (no needle) that the vet gave me. I tucked him under my left arm (I'm right handed) and put the tip of the syringe at the corner of his mouth. He cooperated for the most part and after a couple of treatments, he didn't give me a hard time with it. The trick is to aim the syringe so that the liquid is headed down his throat not onto his tongue (do they have tongues?) I don't know if that would work with a goose or not. I don't think the injectable is the same stuff is it? This was that awful pink stuff they give little kids for strep.
Good luck with the meds. Poultry is even worse than kids when it comes to giving meds.
