They don't seem to be offended by the weird food mixes we are. Kind of like kids, who will eat all sorts of weird stuff together.
We have two buckets next to our kitchen trash, labeled 'chickens' and 'goats'. The vegetable and fruit and grain scraps are split between the two, dairy goes in the goat bucket, and meat/fish/eggs go in the chicken bucket. When we clean out the refrigerator, they get all sorts of crazy snacks. How about green bean/sloppy joe mix/milk/marshmallow/spaghetti/orange juice soup? The goats went nuts over it! he chickens are a bit more picky, but they never got table scraps before we got them, so they are still learning. They love salad or watermelon, or beef, but that's about all so far. I have a hard time even getting them to eat bread! Silly chickens.
