as for the farmers market be sure to check with the sellers, here in Eugene they keep a big tub of carrot tops and mashed berries and other bits behind their table and if you ask they will let you help yourself to whatever is there, be sure to bring your own bag so that you don't impose on them, since most of what you get would just be composted they are happy to give it away since they ususlly have enough compost as it is and if you take it they don't have to lug it home - last Saturday my babies got about a dozen HUGE strawberries (that I cut up so everyone would get some) and the usual carrot tops (that they love) plus various baby greens and some small carrots and radishes that I grate with a cheese grater for them. yum, they always know when I have treats and come running.
