BCM, hatched from shipped eggs. Nobody else has this, but it almost looks like angel wing. I have vitamin B in their water; should I wrap it like a duck?
I don't believe chicks get angel wing. Usually what happens is those first few feathers just don't lay right. They are temporary and will be molted out.
Also sometimes they are a bit heavy to the chick because they aren't used to the extra weight so they don't hold them tight against their body. I personally wouldn't worry.
