Having crossed two Mack Snow Blizzards together (one of which may be a super), I am having a hard time identifying the offspring.

Having done the genetic homework I realize the offspring could be:

25% Blizzard
25% Super Snow Blizzard
50% Mack Snow Blizzard

The eyes appear to both be solid black, which apparently can occur in any of the above possibilities. My question is how in the world do you tell these apart?

Any help would be greatly appreciated.
