Hi UnlabeledMama!
:welcomewagon:
The markings make me think English Spot is a possibility, or even Checkered Giant. They have the butterfly on the nose, eye and cheek spots, colored ears, a strip of color down the spine, and in Checkereds, spots on the rear flanks, while English Spot have scattered small spots along the sides. Their markings are not up to the standard for either breed, but they do have elements of the pattern.
Do you have any idea of their age and current weight?
To me they don't look racy enough to be purebred, but maybe they are mixed with a meat type rabbit.
They certainly are a pretty pair of rabbits!
:congratulations:
