Bright yellow chick?

[SweetPeas11]

We purchased a bright yellow chick (pullet) that is feathering in bright, clean white. she is about 10 days old. The farm supply store said she was an "ideal" pullet that will lay white eggs. I am new to the chicken world and have no idea what this means. Any help out there? Thanks!

White leghorn probably. I have one, I think, that is 6 weeks old.
