This is a 4 week old chick sold as a blue rock pullet from tractor supply. I'm starting to wonder if he/she is an andalusian instead of a blue rock? And thus perhaps a cockerel? I started getting worried when his/her comb turned a bit more pink at the base. Unfortunately, we are in a suburb and cannot keep a rooster, so I'd love to know as early as possible so I can start searching for another home if needed.
