Okay, I was told that this stuff would work on tapeworms for my chickens, I just cant remember who on here told me. I bought a bottle, $20 for a 4.2fl oz. bottle. I just need to know how much to mix in a gallon of water. Im going to give it to everyone. Ive got juvies, and bantam silkies, as well as adult birds. Any help and advice would be appreciated.
