I've heard that Guinea Fowl can be good guards, and they make a lot of noise of something's happening. But I've also heard that "something happening" can include a neighbor coming home in their car, an ambulance 2 blocks away, or a tree moving in the wind... Are they just plain LOUD for no reason or do they really know what's normal and what's not, and learn to scream at what's NOT normal? Would they possibly be OK to keep in a semi-rural neighborhood with 1/2 acre lots? My neighbors don't mind my roos, they do hear them but they don't mind them, even though I've got one dumb one that wants to crow at 2 AM. Also, can they be kept in with chickens, in the same coop and run?
