Lol! That's funny cus when we first got our ducks home (we're new duck owners too) the FIRST thing ours did was try to eat the acorns. They would pick up one, chew it for a little bit and then give it up. When it dropped out of their mouth, another one would come along and pick it up. It was like they were playing pass the acorn. I thought it was weird (and hilarious) but apparently it's normal lol.
