I was going thru my Duncraft catalog, and they have -eek- roasted mealworms. Wormy things kinda gross me out, but if they're good for chickens as a treat, would this be good for them? It's kinda pricey. There's about 10,000 whole or partial worms in a 16 oz sack for 39.95, but it would last long if it's for treats. OR is this not for them? Thanks in advance!
