Perhaps, the woman you got them passed off some Brahma/Cochin crosses? After all, they were packing peanuts, maybe because the hatchery knew they had a goof up? I would say a Dark Brahma/Silver Laced Cochin cross.
Actually, if you look at the feather coloring, I would immediately go with a White Laced something. But the head and comb are more Brahma-ish unnless they are actually pullets. I have never seen a Brahma with coloring that was that off. The body is not of the Cochin type either, it lacks that poofy feathering around the thigh.
Keep taking pictures and when they have mature feathers, show us what you have.
