First pic pullets, mixed breed or ee maybe. Second pic the brown one looks pullet, the white and black bird looks like a roo. The brown bird could be a sex link or ? The black and white one puts me to mind of a weirdly marked slw. Third pic a funky marked Delaware roo? fourth pic may be that same bird, the other two look like pullets.
obligatory disclaimer--you already know better pics would help a lot!
