No, I know LOL, just read too many worm thread tonight.
How many drops in the eye?Valbazen isnt invasive if you follow the directions I previously posted, it'll kill the eyeworm...you need to read what the eyeworms lifecycle is to understand why you need to treat the eye, then dose internally. It wont hurt them, it will save your chickens from going blind. Redosing 10 days later breaks the worms lifecycle. Ivermectin or any other product on the back of their neck will NOT kill eyeworm. Good luck.
