Probably supposed to be blue laced gold. Immature feathers in hatchery birds are not stable enough to pinpoint when they are young like this, unless someone has a lot of experience with that specific line of birds.
It looks like:
1. Wyandotte cockerel due to dark male type feather color.
2. Welsummer pullet.
3. Wyandotte cockerel, pointy hackle feathers indicating male feathers.
