Seems like you should add grit if you are adding all that.I like to add in a handful of alfalfa hay for them to get some green stuff in their diet. You can put it in a bowl or make you a hanging net holder like for horses in miniature. I also put in suet cakes you can find for bird feeders. They come in all sizes and varieties. Mine cost less than $1 each. It's to give them something to pick at. This gives them some added calories and it keeps them busy.
