I have and have used Wazine, valbazen, Zimectrin gold only because I wormed my chickens did my water fowl get wormed, now I use a natural approach by adding chopped pumpkins seeds and cayenne pepper to their fermented feed and givng that every 3 months.
Lydia, I know many swear by the "natural" methods but please be careful as I have seen many flocks who the owners thought they were using natural dewormers only to have a heavy load of worms in the flock. In general it is best to have a fecel done before ever deworming blindly so you know what you have and use the right dewormer
