I love guineas but I don't keep them anymore, as a nightshift person I couldn't sleep for their "alarms" which they seemed determined to make right outside my window, guess they knew where I was, lol. Guineas don't seem to do well in confinement esp with chickens, they like to be in a group in my experience they always hid their nests , never in the barn, we always kept a hen to hatch and raise the keets, as a hen had better success at raising the most keets, the guinea mom's wanted to wander about the place dragging keets along. As keets they could be quite bullying too, in our experience the lighter colored ones got picked on as well as anytime we tried to keep a chick with them. All this said I still love them and if I didn't have to order so many from a hatchery I'd probably be tempted. This has just been my experience with guineas in the past I am by no means claiming any guinea expert knowledge.
