The area under my hen's eye is swollen, and the eye itself is watery and kinda cruddy. Her head doesn't smell very good, either. This started a week or two ago. It initially looked like her eye was irritated from getting some dust in it, so I flushed it out and she seemed a little better, but now it looks worse. She doesn't act like she's sick, though, she eats and clucks and moves around like she usually does. I have some Tylan 50 and diabetic needles and syringes. Should I use this? Or is there another medication I should use for her? Thanks.
