There are many things you can ‘recycle’ from your kitchen ‘waste’. Some of those things are vegetable and fruit cuttings. These range from the orange peels, banana skin, garlic and onion ends, broccoli and cauliflower ends, sweet potato peels, any vegetable stems etc. I normally feed them as treats as and when i have enough to be sure everyone has a small share. You could also feed them old bread which i dry out in the sun, but serve only a very tiny bit for each because there is only a few slices to share amongst so many.
