I've read that chickens will control june bug larvae, the big white grubs in the soil. This is our second summer here and we put in a garden last year in a new spot. This summer when digging in the garden I could dig one shovel full and easily have a dozen grubs turned over. Now I didn't want to let the chickens in the garden during the growing season. They eat everything I want to eat, and destroy the rest. So if I put them in after the first frost and thru next spring up until planting, will they help control the grubs? Or do they need to overlap during the summer months? Any one have any experience using chickens to control these grubs? Thanks!
