I have 1 one year old hen who is wheezing and has some bubbles in her eye. Another year old hen that is wheezing and sneezing. I also have one 10 week old chick that is lightly wheezing. I separated them and used some vet rx for now. I’ve heard your supposed to give them Tylan 50 is this correct? Is their an antibiotic that can go in their food or water instead or is there only the injectable kind? Im a little scared of needles and I’ve never given a shot before. I don’t know how. Any advice would be helpful.
