What colour would I get? Breeding polish colours.

[Meredith MMH]

I have a Large White Crested Cuckoo polish cockerel and some WC Black, WC Blue and WC Cuckoo polish hens. I'm going to hatch some of their eggs but I don't know what I would get out of the blue.

Cuckoo cockerel + Black hen = dark Cuckoo

Cuckoo cockerel + Cuckoo hen = light/dark cuckoo

Cuckoo cockerel + Blue hen = ........?
Does anyone know what I would get out od these?
Thanks, Meredith
