I have Gapeworm on my property big time and have had turkeys and chickens die from it. I have found that fenbendazole in the pellet form will get rid of it. It is a dewormer that works well. They sell it at stores like Tractor Supply or feed stores. You can give it to several kinds of animals. I add it a little to the feed for about 6 days, then I wait two weeks, and then I add it again to the feed. This is so I can kill the eggs that have hatched later.
