I just set a couple dozen guinea eggs under 2 chickens. Three years ago I purchased 20 keets, but lost all but 3 the first year to predators. The three that are left are predator savy and do a good job on any kind of insect, especially ticks, scorpions, moths, wasps, etc. I haven't seen any action on snakes, but I haven't seen any snakes, either. Same with mice. They require very little grain and don't mess up the yard like chickens do. Mine roost in the rafters in my pole barn, so owls aren't a problem, just gotta scrape the concrete floor daily, but that's easy enough. They get along fine with the chickens and geese, but I don't have ducks. When I had my flock in FL a few years back, somebody was always causing a problem. Usually it was a drake. The guineas I had there would also gang up on any free ranging rooster. The flock, small as it is, here in GA, get along with everyone. I'm hopeing the new keets will be as amiable when they mature. I can't seem to hatch keets from my guineas as any nests are destroyed by predators within days. Guineas are the clowns of any yard and the neighbors always look foreward to seeing them. One of the problems that many folks have is that even though guineas can fly as well as a pheasant, they would rather run than fly from a dog, making them easy pickings. I have a dog that grew up with them and likes to chase them playfully on occasion. My guineas have learned to fly from him and that lesson has probably saved them from other predators many times. Guineas are noisy, but they calm down as they mature, to the point where they aren't as obnoxious. You will learn to enjoy even their racket. Good luck with yours.........Pop
