I do part time work for a caterer. I always bring home scrap veggies from salad and cole slaw and any bread or rolls that get stale for the animals (chickens and goats). I keep the good stuff for myself 
My uncle is a hay farmer currently growing oat hay and in the summer he grows a large garden to sell produce. When he is finished cutting hay in the fall and finished harvesting, I go and collect the corn stalks, any veggies and melons left on the vines or that bugs got to and leftover oats from the hay. A lot of that goes to the goats, but the chickens like it too.
