My (I think Ameraucana) hen, 1.5 years old, is going through her first big molt. We noticed some injuries on both her wings, neck, and underbelly. She’s not acting strange, she wasn’t upset when I picked her up and let me carefully look at the areas. Her sister, same breed and age, is having none of these problems. No other chickens in the flock have these problems, not even the other molting chickens.
