A:Answer I've never cooked chicken wings (and I HATE when people don't directly answer your questions!), BUT I can tell you about my experience cooking everything else in it...
It doesn't matter what I'm cooking, I pull the bucket out enough to "shake" it at least once or twice during each use. (I don't pull it out much... Maybe an inch or two, where the bucket is still resting on the lip where you slide it into the air fryer, and just "shake it" by pushing it in and out vigorously enough to toss the food around a little bit; it doesn't take much.) IF I do not do this, then no matter what I am cooking, the portion of the food that is overlapping will not be "fried" (or cooked completely) like the exposed portions are.
This bucket is HUGE, so you should have no problem cooking as many and/or as much as you want to in it as long as you shake the contents a couple of times. (You don't even have to stop it; just pull it out, shake it, and push it back in.)
I hope this helps.
