I had 3 of them many years ago but didn't pay attention to them, except notice that they looked weird near the chickens. Then about 2 years ago, DH read up on their benefits and neither of us could believe it that we somehow had never stumbled upon knowledge of how we could get so much help in the garden, naturally + have a bird that taste better than chicken, which eventually needs almost no food and has a decent amt of eggs.
We started with 15 but due to freak accidents we are left with 6 of our originals, but we did reproduce quite a few. We expect our plucker to come in Tuesday, so I will be slaughtering all but the breeders, to decrease expenses and fill the freezer, at which time I will process drakes and goslings also.
Relating to other guinea matters: they are mean to the chickens, but so far I haven't had any fatalities. I would only need to put my foot down and finish their own private quarters and then I could keep the chickens cooped away from them and use the guinea for what I got them for. They do work in the garden because they fly much better than the chickens and they go to work by day.
I do find them stupid sometimes. They get caught on the wrong side of the fence, in my sister's yard and can't figure how to get in the coop and go back and forth until instinct tells them to go up and roost, then....'Oh look!!! There is our home!!!" Stupid. But I can deal with it cuz they are keeping the bug problem under control. I sometimes think that I can decrease my chickens to only what I need for home use eggs and increase my guineas and do better. Better garden, less feed, better and cheaper food.
You will want to coop them for the first laying season, except maybe a few hours in the mid afternoon, when u sure they finished laying. When they are in a habbit of laying like a chicken, you might be able to chance it to let them loose.
Best you read up on it. There is some good reading on the subject. In my experience, you can get all that the books claim from these birds. I know freak accidents can happen, but you gotta be fair and ask yourself, 'what could I have done to prevent this?"
