Wyandotte or not?

[chx3to10]

i bought three SLW from feed store, one on right I thought at first a roo (2 look this way) but then I read wyandottes have yellow legs and a rose comb, these two have black legs and a single comb! What did I end up with!? As chicks they all looked the same!

"wyandottes" are top three, white faced, the front two are barred rock for sure, they are not birds in question. Any help please

The black one looks like it might be an australorp, could be a black sex link if any red appears around the chest/neck area.

I think I see two SLWs, an australorp, and two barred rocks
