My duckling is just turning 4 weeks old and everything has been going pretty smoothly, but I have noticed that one of the growing wings (the one on the left and picture attached below) is growing a little bit upwards, and I wasn’t too sure of this is early sign of angel wing. I have still been feeding her( we think ) chick crumb mixed with oats (80:20) ratio. But I would appreciate any advice on if it is angel wing, and if so what would be the best way to deal with it.
