|Gynandromorph chick at 5 weeks|
After posting some information and pictures in their forum, I got feedback that it could be a gynandromorph -- half male / half female. Apparently this can happen if an egg was fertilized by two sperm. Here are some photos. The left side looks male with a red waddle and thick yellow leg. The right side lacks the waddle and the pale leg is thinner like a hen would have.
I'll post more photos as this one matures when there's more to see!
