I have ducks and they go absolutely crazy for watermelon. My neighbor gave me half a watermelon the other day because he couldn't fit it in his fridge. I have it to the ducks and they went wild. Luke a cartoon style piranha feeding frenzy. The white birds looked like they'd been drenched in the blood of their enemies. One of them decided to sit in the empty rind after they were done and laid an egg in it, to assert dominance.

They also love birdseed and peas. I had a duck who could recognize canned peas based on the labels and would flip out if he saw me approaching with them. He also adored bird seed and would help himself to the bag if it was in a place he could knock it over. Found him stuck in an empty birdseed bag once. It wasn't empty that morning. Bro was a glutton, but he was a good boi.
