The solid grey chicks seem to have a pea comb and greenish tint in their legs so i am leaning towards easter egger. The chipmunk patteren chick has a single comb seems like slate greenish tint on its legs as well. And the black chicks have white spots on head and breast with black legs shafts on legs with random yellow and pink mainly on the toes but some on the shaft as well. Not sure if anyone has any idea at this early age but its worth a shot! Thank you guys in advanced so much knowledge on this site.
