I reccomend asking your grocery stores if you can collect their produce scraps. I get over 100lbs a week of leftovers from the pre-cut melons and stuff they sell. They throw out a lot of whole watermelons if they have a soft spot or blemish. Fruit isnt a good staple for chickens but it's good for free, also attracts more insects to their area.
