I was hesitant to go outside my direct-fed wormers, and actually decided to give the Rooster Booster worm crumbles a shot. I mixed 1/3 oz to some feed today with a little wheat germ oil. In my opinion, a mini pellet would be better than a crumbled form. Smaller pieces tend to stay at the bottom of the feed trough. I'm glad it works for some of you folks.
