It would surely call for white legs. If you have a great female that's not wheaten, I would use her with no reservations. The male offspring would still be show potential. I just hatched 2 pure wild type chicks this week, I'm excited to see how they turn out. I did want to add JE that your pullets may be part wheaten, if the chick down was yellow with a stripe or 2, they are part wheaten. Based on your pictures, I feel they are part wheaten. If the chick down was brown with black stripes, they are pure wild type.
