I love guineas. Goofy, silly things, always entertaining. Yes, very loud, constantly when they are younger. Negatives: They can be very aggressive to chickens. That's why I no longer have mine. They will attack in coordinated strikes, from all sides, doing bodyslams to their intended victim. I had very tame, sweet guineas...till my alpha male attacked one particular RIR hen and it got worse, then they attacked my rooster.
