What would these crosses look like?

[animal boy]

I have a buff brahma rooster, a white rock hen, a rhode island red hen, and a black cochin bantam hen. I've sen the rooster mate with all of the hens and the cochin finally decided she wanted to become a mother (she went broody). I've look online but can't find anything on what the crosses might look like. Or anything similar. Anyone have any ideas. Pictures would be helpful. Thanks.
