I am interested in keeping guinea fowl. I am in the suburbs. So, if they were raised from chicks and fully comfortable with their surroundings, do they have the potential to be quiet and less flighty? I know they are naturally wild, skittish birds so please tell me if this is too good to be true. I'm looking for fowl that won't wreck my garden and since I am giving away my chickens to a friend, guineas came to mind. Thanks in advance!
