If I were to give it orally I think I would give it at least twice a day.Yes, the Tylan 200 is pretty concentrated to give as an injection into a bird's breast muscle, but you can give it orally. The Tylan 50 is preferable to Tylan 200 for chickens, and turkeys, too, but you don't want to be giving more than 2 ml in an injection--1 ml is plenty.
