It really depends on the object. If it specifically justs says 'touching' or 'contact' then touching it with your wing should work.
Otherwise, most magic items require you to be able to manipulate them which, as the rules are typically written from a humanoid use perspective, would usually mean hands (obviously since you didn't specify an item, we can't tell).
So,theoretically you could manipulate an object like a wand even if you were juggling it since it's in your hands regularly, but I wouldn't let you use one while balancing it on your nose or juggling it with your feet like a hacky-sack.
Sorry to you as well, I had looked and didn't see any responses. So the object in question was much like a crystal ball with a suspended spell or spell-like effect inside. It was effected in a way that only the makers could use them. Certainly in no way as a free action but, they had to make contact with it to make the decision of which effect inside would be used. Like you had mentioned most of the time the reference is toward using hands to make the effect happen. The characters in question were a succubus/incubus duo that would have their hands otherwise busy holding other gear or weapons. Leaving me with the question of whether or not the wings could make up for that. Thank you for the response and sorry again though.
