We love our guineas; we have ten. They have been raised with the chickens since they were day-olds and they're quite bonded to and protective of the chickens; I swear they can count, and if they're missing more than one or two chickens they raise the alarm. They are the first into the run every morning and they scout for danger (and the best bugs). They do need a higher-protein food, though - we're continuing to feed starter even though the chickens into grower age because we need to make sure the guineas are OK. When we switch to layer we'll need to find a high-protein one for the same reason. Either roof the run or clip wings, because they can fly over any barrier, and if you're suburban be aware of noise. So far we've been able to avoid the famous guinea screaming because we keep them calm and happy, and their run is not in sight of the road or someplace they could see intruders. But if they do get worried... wow. I once made the mistake of taking several of "their" chickens out of the coop and the guineas decided that was unacceptable. My husband was trying to yell something to me from a few yards away and all I could see was his mouth moving. That's how loud they are.
