Breed of chicks?

[JDipiet]

Pic 1: Blue Australorp or Rhode Island Blue
Pic 2: Rhode Island Blue
Pic 3: Welsummer (because of the chipmunk stripes)
Pic 4: Isn't this the same chick as Pic 1?

Yes, sorry, look at the added pic.

I didn't know that Rhode Island Blues are Red/buff as chicks! That is Pic 2! Where did you buy these chicks from?

Paris Farmers Union in Maine.
