The mother Earth I'm reading has a nice article on Guineas. You'll want to do your research as they are not as easy to keep as chickens and ducks. I've considered them too. My neighbor has some I think. His first year they got loose and he lost one.My kids have all already been bit multiple times this season. They are all boys and climb trees and roll in the grass. My 5 year old has had Lyme twice now. I am tempted to get guineas.
