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.

I buy the dried milk and make my own yogurt for them...way cheap...they love it and it's great for extra protein for them. They absolutely love dandelions so all I can find go in their run. They won't eat strawberries but love plums and canteloupe. Earlier this spring I planted some oats and clover for use in herbal tinctures and teas, and it turns out they love it! So, next year, I'm going to plant more and some alfalfa as well. We don't have enough room to plant tons of the stuff, but it's a nice, fresh addition for supplementing.
