The major reason I'd consider getting guineas would be to get rid of ticks. Do they really do that?? how many would I need for a 3 acre property. I have chickens, and they would have to share the same coop. When I was growing up we had guineas, so I know they're funny, but they are also noisy, want to sleep outside on the trees etc. So... are they worth the trouble? And if so, should I get only males ( I hear they're less noisy) ? thanks!
