#4, 5, and 6 could be starlight green egger because I have some that look like that. #5 could be a golden comet but they also look like starlight green egger. starlight green egger has four different looks. hoovers hatchery started this breed.
I also bought chicks from tractor supply. #3 is a rooster for sure, some of them look like my chicks, and I have golden comets, and starlight green egger, and blue lace wyandotte and some of yours look like mine
