My baby chick is 6 weeks old and I noticed that one the legs goes outward and the knee area is larger. She has a limp but runs and jumps around with the others when I take her outside for fresh air. She is the 1st born hatch from an incubator of 5. I did watch a video and have her legs taped up so they are closer together. Other than that she seems normal, eating, drinking, pooping, running and stretching her wings while outside. It looks amazing when they are all outside together, looks like little butterflies fluttering in the coop yard.
