I got a day old chick from a neighbor because her hen was rejecting it and my hen had just hated her babies the same day. I put the chick under her and she took it so hooray! Anyway, the neighbor didn't know what the chick was, thought it was a mixed or barred rock. It looked just like my Australorp when it was a chick and didn't have a white dot on its head. Well this "little" chick is getting HUGE and the legs are very black (blacker than my Australorp) and the bottoms of the feet look yellow. Could this be a Jersey Giant? I figured the neighbor would know if she had one of those or not...or maybe she had hatching eggs and they weren't from her chickens?! Such a mystery. Also, could you give a guess on gender? I'm really thinking pullet but it's always good to hear from others. It will be 10 weeks old tomorrow. Sorry I couldn't get better pictures! Since this chick was hen raised its not too excited about humans picking it up!
