I've never ordered pheasants from a hatchery. I've always hatched my own, or from shipped eggs. The problem  with some hatcheries is that they get their pheasants on consignment, so you never really know what your going to get or where they are coming from, If I just wanted ring necked pheasants, I would get them from MacFarlane's, they raise and breed their own birds and have a very strict biosecurity program...less likely to get a diseased bird.
Those 2 chicks are a mystery and most likely a cross between a melanistic and a mongolian, sometimes they advertise them as 'Jumbo's', which are 6 to 7lbs at maturity. Also, they cross a Chinese Ring Necked with a Mongolian and call them Jumbos but those chicks don't have the 'racing stripes' so I'm going to guess they are a Mongolian x Melanistic cross.
I have a Mongolian x Chinese Ring Necked cockbird that is absolutely gorgeous. It happened by mistake when I inadvertently put a Mongolian hen in a pen with my wild Kansas Ring Necked cockbird.
Here's the results:

Here's a pic of a Mongolian cockbird for comparison.
