I am currently raising chickens, ducks, cotournix and bobwhite quail, chukar partridge, and guineas. I need a worm and fungal treatment since all of the birds are free-range and on the ground quite a bit. I've noticed that many people suggest Flubendazole for chickens, but I was wondering if it is okay for use on the smaller game birds? Could anyone help with my dilemma? A reliable place to order offline would also come in handy, as looking for Flubendazole online has proved a little tricky. Some of our birds are a little up there in age range--we had a treatment planned, but it turns out it wasn't recommended for poultry--so please take that into account also. Thanks!
