Gape Worm, treating

[Tricia's Triple Z]

I have Fenbendazole, I can't find the dosage. I thought that it was 1/4-1/2 cc. I'm not sure if I should treat the whole flock (17 birds) I also have heard that it wont hurt them it they are wormed and there is no withdrawal. Any input? Thanks

There is a withdrawal for that product. I'm not sure how long, maybe two weeks. How do you know they have gapeworm? Did you look down the throats and see the y-shaped male and female worm? I ask because it's not a common worm for them to have. ARe they eating straw? That gets stuck in the throat at times and causes them to sort of gag.
