Good helpful people here. I like to simplify things for myself. Lots of different wormers for specific worms as folks clearly discussed here. I like to use products that zap all worms; gape, tape, cecal, etc. The people I know who've used Zimectrin Gold swear by it. I'm glad because it is often carried in the feed stores. I've used Wormazole, Neokil, or Dr. Blues Enzum wormers that must be ordered. I know they take care of all worms. Something to think about when you consider keeping a well stocked medicine cabinet for poultry.
