I bought 2 little chicks ( well 3 actually because my grandson fussed for a little RIR rooster chick ) They are now fathered in but I am wondering if one is a little more boy than I had expected. The lighter colored one has more tail than the other and I have caught the little rooster and this one charging each other with neck feathers flared up. This doesn't seem very lady like behavior . However there is no comb growing . I am just confused as can be .
