Chickens are just as good at keeping the ticks at bay, and they aren't as loud, annoying, or flighty as Guineas. Our neighbor at the end of the road used to have Guineas, and even though he is 1/4 mile away, we could still hear them. SO loud. We have chickens, and we only get ticks on very rare occasions. DS is outside ALL the time, and he never gets ticks.
