My ducks perch up on the pallets I used to make my bins....Don't seem them eating from it often....but def, adding nitrogen to it. Last year Mother earth news did a chicken story and one thing they encouraged was fencing them around compost for a few days so they would turn it up and get lost of worm to eat as rewards.
Well I think i am going to open mine up to them and see how good a job they do. I know there are some yummy worms in there but probably way in the bottom right now. lol
