Hi guys! I'm new on this site. So I have three chickens. I'm not sure what breed they are, but they're all girls. One gray one that'll be white when she's older and two rusty-red ones that will be speckled brown. We made them a perch and they seem to be doing very well, but I have two questions: 1. How do you tell what breed your chickens are? 2. How do you tell how old your chickens are? Thanks guys!!!
