Here is the image from the sex link thread (specifically the black sex link chart). As you can see the list of hens is pretty small while the list of potential roosters is quite extensive.
Your pullets remind me of one of my black sex links (Foxy). Her "sister" Scrappy came out of the same bin but has a more classic appearance (I put her in for contrast). We grabbed foxy because she jumped right up on my wife's hand and had some red down mixed in with the black (which made her easily distinguishable from her sister). As they grew Foxy grew a lot more orange feathers than scrappy. I always wondered about her since she did come from a feed store, but then I stumbled on a some golden laced wyandotte mutt pictures and thought to myself that she looked a lot like those mutts. That just happens to be on the list as a potential father. We don't know her exact mix of course but there is room for a lot of variation. There a great number of potential fathers involved and I don't think the breeder care beyond that they are easily sexed and are good layers. I think the big question may be "who's my daddy?".
