In the top photo it's hard to see combs, but the black and white one looking at the camera has pullet coloring. The orangey ones look like pullets. The black and white one closest to the camera has classic roo patterning. Not sure on the calico towards the back left, unless it's the same one in the bottom photo. Bottom photo looks like a roo so far based on the splotchy calico coloring.
How old are they again?
