Hello all...so I have a little khaki call duck whose cheeks are extra puffy...I just thought it was cause she was extra cute! A lady who raises TONS of ducks saw her and told me she has a severe sinus infection and that her cheeks shouldn't be that puffy! Now I just feel horrible...she suggested Baytril injectable, but that isn't sold in the US anymore, so any suggestion on what kind of antibiotic I can give her and the dosage??? PLEASE HELP!!!!
