My Chickens for Dummies book says not to use even composted chicken poop in gardens where food is growing. I thought it was ok as long as it was fully composted? Is this just in the book because of liability issues? And how can you tell if it's fully composted? We always wash anything we get from the garden, but I like being able to just set the just-picked tomatoes, cukes, etc on the table or counter until they are washed and not worrying about having to disinfect surfaces after.
