It could just be how the wings are laying; I've had many that the wings sort of go straight back rather than curve toward the body; is this possibly what you have going on? If so, it's nothing to worry about.
Are these chicks from a hatchery? Hatch date? Breed?
I am starting to think that it is just the way the wings lay. The more pics I look at of angelwings, it doesn't quite look like. It is a Rhoad Island not from hatchery, hatch date was 9 days ago. This one seems to get picked on a lot by my older ones 5 weeks old and I just want to make sure it's not something they are going to peck at.
