I have several guineas. A pair of pearl that are two years old, a few I hatched this last summer at different times and a couple I bought at the local feed store. My guineas live with my muscovies, chickens, and turkeys at present, we couldn't seperate them out if we wanted to.
Things I have learned from my Guineas:
1) Guineas believe they are superior to every other bird. Last summer my adult male would try to break up fights between my full grown slate toms, it was the funniest thing to watch. Male guineas rarely tolerate roosters fighting either, they act like little policemen, breaking up the fights.
2) Guineas have a true sense of humor. My guineas would go out of their way to wait until 8 in the morning to fly over to the fence and cackle at my neighbor's window every day that he worked night shift. I think they enjoyed his reaction. They only did it when he had to go to work and only quit when he stopped yelling at them.
3) Guineas can be amazingly resilient. Our oldest male suffered a freak accident last summer and literally snapped his thighbone, right above the knee. It was so bad that you could see the bone through a tear in the skin. I was certain he was a goner and had him on hubby's list of birds to be dressed out. Somehow, he managed to hop around on one leg and spent most of his time with his hen by his side in the coop. As he never worsened, my hubby opted to let him be. Eventually, his leg healed on its own and he is still walking around today, the alpha of our guineas... Amazing.
4) Guineas aren't predictable. My guineas believe they are top birds in the yard but have a very strange affection for our goose, we even caught them cuddling with her one night, wish I had my camera with me. Last summer a couple of them adopted the neighbor ducks and would try to sleep with them at night.
My experiences may be very unique with them as I have for the most part always cross broodered most of my birds. When you hatch out only a couple of types of any one bird at a time, it just makes more sense to allow them to be together when they are really small and it seems to breed some tolerance into them.
