Unexpected pied in clutch?

[Bengybones]

I cut this clutch today on day 55, and found something very strange.
The pairing was an Albino Pinstripe Female X Pied Male.
The eggs seem to show: 4 normals, 3 pinstripes, and 1 pied.....

What do you guys think about this egg? It looks to be a high white piebald. Do you think this could be just an extreme ringer?
If the mother is in fact a het, would there not likely be more than this one lone pied when paired with a visual?


Thanks,
