Okay, so I have a small urban flock and have owned them for four years, I have never seen a need to worm, so I never had. But I am thinking I should after a rough battle with scaley mites, I figure I might as well be diligent at all parasite fronts... I've already purchased pour on ivermectin, but I've read about doing wazine first to prevent a overload of dead worms, I honestly haven't seen evidence of worms but I know that doesn't mean they don't have them,,, also I'm wondering if I should use valbazen instead of ivermectin? IAny tips? I'm worried about my 4yr old girls this being a shock to their systems... Should I be worried? Dawg53 if you read this I'd really appreciate your input!
