Those pictures are why I think you have a mix of kinds. I was able to see several colors of down and feathers, several comb types, and several foot colors.Oh ok and did those pictures help?
I think you might have chicks from several different breeds.
Or else you have barnyard mixes, where each chick might have parents who are different breeds, and none of them are purebreds at all.
Since you said you hatched them, do you know anything about the parent breeds?
What color eggs did they hatch from?
