We live on a hardwood tree farm in Southern Ohio, so of course have a metric butt-ton of ticks around the coop, run, and chicken yard. I haven’t seen any on the chickens yet, but pull them off of us bipeds on a daily basis. Is there any insecticide that we can use around the coop that won’t harm the chickens? I don’t care whether it’s all out chemical warfare or “natural,” but I need something that will kill these little blood-sucking monsters ASAP!
