I'm having a hard time sexing my 3 week old barred rock. The large spot on the back of the head is what first scared me, but her legs have dark markings which is more typical in females. I need help with the barring though. please help!!! We already had one of the 2 chicks we got back in may turn out to be a rooster, and it upset my kids so much I would hate for it to happen again.
