We have ticks bad this year in my part of North Carolina. Really bad. I've heard that chickens will eat ticks but mine are only free ranging for an hour or so a day and they're not keeping up with the number our back yard contains. One of my dogs got Lyme disease last year and I don't want to go through that again with a dog, or even worse, a person. That's one scary disease. So, if I put Seven dust or another tick-killing product out in the yard is it going to hurt my chickens when they free range? Is there a particular product that effectively kills ticks but won't harm chickens? Will I need to keep them in their run for a certain amount of time after dusting (or using granules or whatever) the yard but then it would be safe to let them out again? I can keep them in their run all for a week or two if need be. They won't like it but they'll learn to deal with it.
