They say as a supplemental food, 100 once or twice a day should suffice for a nesting pair. At .75 a dozen, I'd have to get a second job. LOL!
LOL!, that sure is too many meal worms daily. BB was there today and there were no meal worms available. So they get a lucky treat now and then. Or are you considering raising them? I read that link and it sounds like a bit of work. Beetles and larva just isn't something I could do. I'm too much of a baby when it comes to that. :)
