I gave my flock Wazine on June 17th, after I discovered roundworms. I'm following the directions on the bottle which say to repeat the medicine in 30 days to break the roundworm cycle. So I want to make sure I wait a long enough time after the next treatment which will be July 17th. I do have a hen that is broody now, But I've been removing the eggs every day (she moves around and sits on the other's eggs). When do you think it's safe to leave the eggs under her? I've heard you can eat the eggs after 14 days. But I read about someone's awful experience incubating eggs after the hens had been treated with Wazine, and I don't want to accidentally do that to my chicks.
