Hi! Yesterday at a bird expo I adopted two button quails! I can't find any good charts on breeds/mutations and I would like to know what they are. 
Button #1 (no name yet!):


Notice that she? he? has a bare back. The breeders told me it's because they pluck feathers to nest, or are too slow. Am I risking anything from getting a plucked one? It's very cute and not too afraid of the camera. Also, I've read that the white patch on the wing signals it carries the white gene.
Button #2:

This one seems to be fully feathered (I've noticed they can hide it pretty well) and since it's white I can't tell if it's male or female. What mutation might it be?
They are housed together in a guinea pig cage. I know I need to boink-proof the roof, but what material should I use? For now I'm just really cautious around them.
If they are both males, should I separate them? I hadn't planned on two cages. What if they're both females, will they have any problems? And if nobody can tell their gender, then any tips?
Sorry for the ton of questions, but there's not too much info on buttons that I can find, and most of the info I've found is from here.
Thanks in advance!
