@ChickyNicky05 I have had this happen with 2 generations of Cayugas. They were on different feeds during development. And some had issues and some didn’t. Right now my smallest duckling, Tiny has it the worst. Her Dad was the first one I treated with a dress sock. However she has siblings with a Pekin Mom, but same Dad. The mixes, had beautiful wings during development and no signs of angel wing. So in my case I believe genetics plays a larger role rather than diet. The left wing has looked worse in each case. And I’ve had males as well as females with the issue. I wrangled Tiny this morning into a knee high pantyhose, but I think it’s a little bit too small since she’s almost full grown now. I plan on taking a pair of those leggings that every one wears and using it. I’m just going to cut off a section by the ankle and slide it over her. I’ll let you know how it goes. I should have had it fixed before now, but with family and other birds with more pressing issues I just haven’t.
