I've read till my eyes are crossed and think I have all the worming for chickens straight, but I have a few questions. We use Fenbendazole as a first time safe wormer for roundworms for our tiny miniature foals, so why can't the same product be used instead of Wazine 17 as a first time wormer for my chickens that I plan on first time worming about now? Is Valbazen the only safe drug for chickens that will target tapeworms, or can Praziquintel (sp) be used safely also since most of the other livestock wormers seem to be okay? I always have a lot of Probios paste in a tube around and wondered if I could use that instead of yogurt? I can't get my girls to eat bread, yogurt, cabbage, oatmeal, or lettuce! They run like I am trying to poison them!
