Broody BO hatched keets. Colors?

[marcym]

I have a pair of guineas, but they never get close enough to ensure their true colors. My daughter found their nest, and I stuck eggs under my broody BO (since the last time momma sat for about 10 days, then left them all) My question is, how did I get three different colors of chicks? After looking at the color charts I found in a thread, I have two royal purples, one lavender, and two whites so far. Is this possible????? I will try to post pictures tomorrow, but these chicks look nothing alike even though they have the same parents. Please, clue me in.....

I think that means the parents weren't pure, even though they may have looked like it.
