Tylan 50 should be given with a 22 gauge needle, injected 1/4 inch into the breast muscle. This is more difficult with bantams. Dosage is 1/4 ml for bantams daily for 3 days, and no more than 5. Dosage for standard birds is 1/2 ml and 1 ml for over 5 pounds. Some give Tylan 50 orally, when not comfortable with shots, but an injection is best.
