Even if it's the "same batch" I'm standing by my previous statement. The first pic, and now the latest, look like an almost prestine white to me. The 2nd looks a bit more yellowed. Also, the combs are exactly the same as mine. The first pic (which I think is the white leghorn) is much larger, redder, and more defined. The second pic shows a much shorter, less developed, comb.
I'll try to take a couple pics in the daylight tomorrow. Both to illustrate my point and hopefully to get two of my girls identified.
