Hi! We have a 4-week old RIR chick. "Her" feathers are coming in, and for the first time in my experience, some of the tail feathers are curled downward. Also, "she" has a much livelier personality than any other chick we've had, exploring, jumping, generally being much more animated and fearless. Is "she" a "he"? Okay, figured out the pics: This is Tawny at 4 weeks Thank you for your help!
