If I remember right, the yellow legs are recessive and therefore partially sex-linked. Meaning a male can show yellow legs but also carry the white-legged gene. Females will show the white. So if you have white legs showing up in your flock you have to do test matings of the males to be sure to breed it out. I once read a chart of how to do that. I think some hatcheries are possibly crossing Light Sussex into their Delawares to get the color of the feathers more right (and probably also to make heavier birds?), but that sacrifices the color of the legs.
If it's just a paler yellow on the females that could be a non-issue ... just an expression of how the leg color works on females with other complex color genetics at play. But it's still probably something you could breed away from if that's a priority. Here, the better the leg color of my females the worse the feather color.
