We feed them to our monitor often, but we remove the yolks.. most of the time. Monitors will eat as long as you keep feeding them, so they typically have their life spans shortened by obesity. We feed 2-3 eggs without yolks once a week (we get them from his parents, so they vary greatly in size), in addition to his mice.
We've never fed them to our beardie, though. The only reason I like feeding them to the monitor is because of the protein. I don't think our bd would like them..
