You never disappoint, Cherry!I see no male saddles, but the comb is suspicious. Likely a male at this point.
If he is indeed a boy:
Barred rock: Cross would be sexlinked. Males will be barred and females wouldn't. He looks like a pure AM to me, so the pullets of the cross would lay blue. This is true for every breed you cross him with. They will have modified pea combs (highly likely).
Silkie: Offspring would be smooth-feathered. Not sure what happens with a frizzle though. Again, all pullets will lay blue.
Australorp: All I know is that the pullets will lay blue and they will have modified pea combs. Not too sure how extended black works.
ISA Brown: Some will come out dominant white with leakage. None will be sexlinked.
For most of the crosses, I would expect lots of different colors to pop up, I just can't pin point them.
