With that info I can speculate more about his sire and dame.
Sire(Father) is a Wheaten Maran and Dame(Mother) is a Cuckoo Maran. This produced a sex linked cross. Sister is black and He is Single Barred(only one copy of sex linked barring, inherited from dame).
He has 50% chance of passing his...
That rooster has only one copy of the barring mutation and one copy of the Extended black mutation.
He is likely the result of a cross between Cuckoo and Wheaten. So he is likely E/eWh and B/b+
