We have a 4 acre farm that has ticks galore and I have had Chronic Lyme Disease myself for years already. We just bought this place and we have 3 kids and 3 dogs who I am worried about. So, I want to try some Guineas for tick control. I have heard that they can be loud and I really don't want many. Do you think even just 2 might make some sort of difference? I really don't want more than 4 of them.
