Just got three pullets and a duck from the poultry show. One of the pullets is sick now with a respiratory thing. My first inclination is to use Tylan in the water of all, since they are together, but I can't remember the dosage, and the bottle is not much help. Does anyone know? I also have Ericin, Sulfatrim, Ls50, vETrx, Cipro, Duramycin. Not sure what would be best? If no one knows can you at least give me the dose for the Tylan so I can get them started on something???? My daugher will be very sad if we lose the duck, we all will. Help!
