I like to keep a small bucket and garden pruners in the car and will stop along side the road (I live in the country between farms) and cut long bunches of flowering clover for the chickens. I do a lot of what everyone else mentioned as well --- saving kitchen scraps, adding newly mowed grass, etc. I also get the end 1/3 of romaine lettuce from a small deli in the building where I work --- they save them for me after they cut romaine for their premade salads.
