What breed are these?

[Hennifer73]

I was wondering if these are CornishX? Or? They were all supposed to be pullets but, anyways some I got are boys. So the 2 whitish/cream ones are what I want to know about.

How old are they? Are all the ones in the pictures the same age?
Cornish Cross grow really fast, so pretty soon they're much bigger than most other kinds of chicken. White Rocks and a few other breeds can look similar, but don't have the explosive growth rate.

6 weeks tomorrow on the 2 white ones and that cockerel in coop is 6 weeks as well.. The 3 black sex links in coop are only 5 weeks.
