We found the perfect high-protein snack for our BAs--a shovelful of red wigglers from our vermicompost bin. I am sure that we have hit stationary phase in the vermicomposter as there are gobs of worms in there--a never-ending supply. My 1 and 4 year old like to take an old pizza pan and put a shovelful of worms and cover it with weeds and flowers and feed it to the chickens. They call it worm pizza!
