What could we get crossing splash cochin with..

Hi everyone

We have a splash pekin rooster (I think you all call them cochin) ..Just wondering if we end up keeping him what we could get crossing him with our girls??

Our girls are-
Buff, silverpenciled, and black..that were supposed to be mottled and cuckoo..and if he is really keen we have big girls too (a rhode island red, orphington crosses, silverlaced wyandotte's, oh and one white silkie and one black with white splashes..

Thanks!

 

I also forgot my favourite little girl my spangled cochin (pekin)
