This is a 7.5 week old olive egger chick that I am having a hard time trying to decide if it is a he or a she. Some days she is more aggressive and acts very much like a cockerel and other days not so much. She started out slower getting her tail feathers but in the last week has almost passed some of the other chicks in getting her feathers. She has absolutely no comb or wattle growth and no red or even pink coloring. Would love your opinions.
