Take your bird’s feeder/food out of their cage.,
Take it either outside or next to a garbage can.
Gently blow on the food.
,, Parrots crack their food, (whether it’s seeds, shells, or any type of cracker, treat, etc.) and the shells should just float away. Keep in mind that this will not work for any bird that uses grit to dehull their seeds, and will not work for pellets.
