I dont feed flax either, but 1 cup seems like it would be WAYYYY to much for a miniature. Remember....donkeys are VERY easy keepers and dont really need any grains, and if yo udo want to grain 1/2 c. is more then enough, for a complete feed. I did feed Platform for awhile, and I know that contained flax, but I am sure it would of just compared to probably a teas to a tablespoon per cup, most good packaged feeds have it right in, so there really is no need to feed it seperately. I dont really know of anyone who does feed just flax to the donkeys to ask either. Sorry, cant help you on this one..SHAWNA....what about you??? Do you feed it??
