Is there any pattern to the cuckoo vs. barred, yellow vs. white legs? Such as, the cuckoo ones all have white legs while the barred all have yellow legs?
If so, then you have Barred Rocks (yellow legs and defined barring) and Cuckoo Marans (pink legs and cuckoo, not barred).

Barred Rocks with pink legs would be a DQ for show.

This.

some of the hatchery barred rocks will have messier barring at times, but as they fully feather out you'll be able to tell the difference. Cuckoo pattern has a V shape to the white, barring is straight.
