I bought guineas last August just to keep the ticks under control. Yes, they have helped DRAMATICALLY. We noticed the ticks were better this year until we locked the guineas up for a while to plant grass seed. I can't wait to let them out again. Guineas can be loud, but not all of the time. I understand they are louder when they are young (just like teenagers), but they calm down a lot when they are older. Ours are 9 months old now and a joy to have around. They are hilarious to watch. We are working on hatching a second generation around here. They make noise when something startles them, and when it's bedtime, but they settle in pretty quick. I wouldn't let the noise scare you, unless you have very close neighbors that may not appreciate them as much as you do.
