TN, I think the leg color is something that is thought of last, but you're right, they are supposed to be bright yellow. One of my girls in particular has more dull/dusky yellow legs, but overall, I'm pleased with the leg color of this batch. It's just one of those traits you cull for, but there are so many traits to get right with these birds, that it's hard to get them all correct at the same time. Guess if you did, it'd be a perfect Delaware, right? I'm glad you're enjoying them. It's fun to watch their markings evolve.
