I bought rolled oats for the ducks. So I gave some to the geese. They just picked them out of their feeder and dropped them on the ground. I steamed some oats for the ducks and gave a couple of spoonfuls to the geese and they gobbled down every last one. A scoop of oats in a bowl, cover with boiling water. Allow to cool completely and feed. By the way, the ducks cleaned up every last drop, too.
