I'm guessing he's likely a mojo het pied, but I've still never seen a mojo het pied with any significant pattern changes. She seems like she may have a ringer as well after further inspection. I cant wait for them all to shed! Maybe this can clear up the possible genetics:
Possible Sire 1: Mojo Het Pied
Possible Sire 2: Het Pied
Dame: Mojo
