MPC has so many "designer" crosses they've come out with, it's going to be all but impossible to identify some of their birds. They're not "breeds" per se, so don't have a standard look.
Saying a bird is poor quality isn't meant to demean. It's simply a fact that most hatchery birds aren't...
Profile pics of the bird standing naturally are best, it's hard to see body shape and stance when the bird is being held.
Source of the birds helps narrow down breed, also.
