Silke cross, what is other half?

[Oncoming Storm]

So, a little over a year ago we bought a group of chicks from a breeder and it included two Silkes. My golden Silke died within the first day from shipping stress because we moved into a new house and didn’t have sugar. Anyways the remaining Silke grew up to be a beautiful black roo that doesn’t look like a silke. I’ve recently been told that he’s a cross and and am interested to see if you guys can give me any ideas on what breed his mum may have been. (Picture was taken yesterday so its current)

I would like to add that he’s over a year old and his spurs still haven’t grown in

It's almost impossible to know unless you know the possible parent breeds.
