Agree with this mostly. McMurray has Whiting True Greens instead of Starlight Green eggers and Blue Sapphires rather than Sapphire Gems, but they're essentially the same thing for the purposes of a backyard flock. OP, can you get side shots of the birds lacking them, especially that last mostly black one?
Most chicks hatch with dark eyes that turn bluish, greenish, or brownish until they're several months old. My Ancona didn't get her orange eyes until she was about 5 months old, looking at her pictures from when she was that young. Baby and juvenile eye colors are rarely what their adult eye color will end up being.
Edited to add some thoughts.
