I'm sorry I can't see much with you holding them other than the combs are fine...not looking roo-ish yet.
As to coloring...the first appears to be a Cuckoo..grey/white legs with a bit of pink between the toes...it may be the sofa she is standing on, but could be the more upright stance of Marans.
The second could be as well, but I can't see her as well with blur, and I can't see her feet.
The third has more of a barring appearance, but not strongly, and I can't see the feet.
Are you sure the 3rd was *all black* as a chick? With that much barring, there would have been a white head spot.
I don't think these are pure bred. I think they are somebody's backyard specials.
With that in mind, nothing screaming roo right now. Combs are not red at all, and still within the norm of female. Don't go by barring/cuckooing, light/dark, as these are not likely purebred so the colorings will be off making it pretty impossible to tell gender from appearances.
If I had to guess...I'd say the top 2 are likely female and the bottom Lucifer is likely male.
Time will tell.
