I buy 1.5 Ounce Freeze Dried Mealworms in ReSealable Bag from the feed store. I think the name is Fixins Mealworms. They are farm raised mealworms are quick freeze dried to lock in flavor, freshness and nutritional value. They are 50% protein, 25% fat and preservative and additive free. My flock loves them - sort of a chicken potato chip!
