Hi Trsturself,
The blue one looks like a Blue Orpington to me, because the legs are pink and slate combined.
The middle one looks like a Welsummer to me, because the markings and I don't see any blue at all in the chick.
The last one looks more like a Plymouth Rock to me, because of the white around the egg and the legs are not too yellow.
Just my opinion of course. Enjoy your pretty chicks!!
