can you tell me what these are?

I'm thinking that these are all going to be the same type of chicken, except perhaps for the whitish one? I was hoping to have an assortment but that's alright.

fwiw they were marked as red pullets and assorted pullets at TSC.

I would guess they are red sex links, and the white ones are leghorns.

How old are they?

the ones in the first picture are about three and a half weeks, the other ones are about a week and a half.
