Buttons make good cat food. Perfect size for a meal. Other than that the only good suggestion I've heard is to wrap them in cheese cloth and very slow cook until the meat falls off and then seperate it to use. However that ignores all the work attempting to neatly get the internal organs out of something your finger doesn't fit into the body cavity of. Quail are small enough as is. It's not profitable to raise the smallest of them all. Plus I always get too impatient while trying to break enough button eggs to consist of more than one bite. 20 eggs later I end up adding a bantam chicken egg or 2.
