Keep the one that you like best and/or is best with the flock. As far as future egg color goes..???? I have a slw/ee pullet that has the beard, muffs, and green legs. I was hopefull that she would lay olive eggs because of all her ee features, but when she started laying it was dark brown eggs. It's kind of funny though because all my slw lay really light brown eggs and her mom lays a pretty seafoam green egg.
