feather footed I say cochin, what color is the first chicks legs and can you tell what kind of comb? not sure on the little blue on either, what kind of comb? that might help narrow it down. WHere did you get them? sometimes if you get them from a feed store they only order from on hatchery and you can go to hatchery website and see what breeds they carry
TSC usually gets chicks from Ideal I think (not positive) but you can check their site and see what they usually carry, if they aren't bantams then they are probably dual purpose of some kind....my best guess for the first chick would be wyandotte (if it has a rose comb), and I am kind of clueless on the blue one
Is the first one a bantam? If not, it looks a bit like Silver Lakenvelder. The 2nd one looks like a Barred Rock or Dominique....is it really blue or is that just the lighting?
