Can I use it for deworming my chickens? It was the only thing the store had available for chickens. They had Flenuraben (spelling?) but only in giant tubes of paste for horses and cows. The Piperazine-17 said to give 1 fluid ounce per gallon of water to chickens. I hate all these chemicals (normally I go organic) but my 3-month old is thin and has worms -- it's a rooster so I'm not worried about eggs (though meat at some point probably in 3 months or so). If the piperazine is not ok, where do you get other drugs from? There is no TSC here.
