From what I can see it looks like you have 3 lavenders and the rest are pearls - for colors.
The French part refers to a specific breed that is fast growing and about a third larger in size than regular domestic guineas. They were developed in France as a meatbird. If yours are French pearls, they will eventually be bigger than the lavenders and will hop and glide more than actually fly.
There are also Jumbos that are sold in the states and as far as I know, they only come in pearl and lavender colors. My lavender Jumbos fly like regular domestic guineas and I don't really notice a big size difference like I did with my French.
Beautiful keets! Enjoy!
Here are photos of some of my adults - a male French pearl and two lavender Jumbo males (in the snow).
