I agree that you have some gold-laced wyandottes there, but the pullet in question looks to be at best half. I would guess the product of a gold-laced wyandotte hen, and a single-combed rooster. She does have the yellow legs and some gold and lacing in her feathers, but the muddling of the pattern suggests a mix and her single comb is an unlikely pure wyandotte. I have seen on rare occasion wyandottes with a single comb, but looking at her I would definitely go with half-breed.
