Hello all! I discovered today that my flock has worms, the look like round worms. A week ago I began to have a huge decline in eggs. I have Wazine17 but I've heard it has a permanant egg withdrawl, and that alot of people swear by Ivermectin pour on. Is it Ivermectin Pour on for Cattle? What should I treat their area with so they aren't reinfected?
