[Mr chickenmath]

I have some straight run chickens and one of them is pure white with a faint black color on its chest and I don't know what it is.

I also have a dark reddish color and I don't know if it is a red pullet like my others or if it is something else.

last I have a chicken that looks yellow and that is it no other color and I don't now what it is.

any help please

Pictures, the age of the bird as best you know, and where you got them from are all good info for us to help you figure things out.
