Dec And Rec. Pied As A Chick

I've got a clutch of 4 chicks in the nest. Fourth and last one hatched just a moment ago and I noticed this one having very deep dark eyes compared to the others. I even thought earlier if some of the others were cinnamons having not so black eyes, but I checked some cinnamon chick eye colours from photos and these had not any red to be seen, only "blackish". But the last one now had very black eyes.

I wonder if anyone has experience on DEC and rec. pied chicks eye colour, do they differ from normal as very young? I know rec. pieds at least have that reddish tinge in their eyes even as they grow up, but I've never seen a DEC.

Reason to believe any res. pieds or DEC to be in the nest is that the cock is possibly a dutch/clearflight split rec. pied and the hen is normal split recessive pied.

Thanks for any answers.
