My favorite little pullet has a respiratory issue and her sinuses are swelled up so much that her eyes are swelled shut. I'm getting her some Tylan 50 today when i get off work, I put electrolytes in her water, gave her a dish of medicated feed and I've got her in the house to watch her. My question is: Does the Tylan 50 have to be injected or can I give it by mouth. I'm not a real big fan of needles so if there's an alternative I'd much rather do that. But if it has to be injected, where exactly do I inject and how long of a needle?
