There is.Then that makes it simple to administer with an eye dropper.
The only concern would then be the concentration of the liquid . I thought the posts above mentioned it was also in a powder form?
There's injectable Tylan50 or Tylan200, both are liquids which can be given orally. You would just draw up the correct dose in your syringe, take of the needle and direct oral dose the bird. No need for an eye dropper.
Tylosin powder is also available. It's sold online. Dose is 1tsp per gallon of water. Dosing is dependent on the bird drinking the medicated water throughout the day during waking hours.
It's not complicated.
