I tentatively bought one packet of these when I first got hens, and now have to regularly buy a big bag. A little scoop of these scattered around some lawn clippings in the chicken run gets them all so excited and keeps them busy scratching away on the hunt for their mealworm treats all day. They smell toasty in their container, and not as gross as I thought they would be. I even ventured out into the mixed insect bag once or twice. So lovely to see the hens eating things that are more aligned with a natural diet for them, and to see them happily and busily scratching at the ground rather than being bored or attacking each other. i scatter the mealworms around so they really have to go looking for them, rather than the predictability of a pellet chute. Very glad I gave them a go as they are now a regular staple treat. I am buying my chickens' love one mealworm at a time. :)
