Couple of my chicks have eye worm so bad I thought I would have to cull. After 24 hours of treatment- they are almost back to normal. I even had one chick that could not hold it's head strait- always tilted upside down and running in circles. Today was the first day in a week that it was up right. Amazing product!!! Great price on Jeffers- can't find it cheaper anywhere else. Thank you so so much!!!!
