What breed are these chicks?

[MoparGirl89]

So they came in labeled as blue cochins, which they are obviously not. My feed store let me take them for free and ordered me my blue cochin who came in as a blue cochin lol. But now I have no clue what these chicks are. The one has brown/ gold flecked throughout its feathers and the other is pretty much all grey and black. Any guesses?
The first 2 pictures are the one with gold and the other 2 are the one with just grey and black.

You will need to wait until it matures more. It could be a blue andalusian, or other blue breeds, or mixes. Too hard to say until you can see the body type.

How did you figure out they're not cochins? Those featherless feet?
