Ever fascinated by the circle of life thing evident on the land, we decided to give these evil forest tent caterpillars (Malacosoma disstria Hubner) to the chickens as a treat. So we hand picked them from their webby nest and put them into a plastic tub. Then we put the tub in the chicken run. Bloody Beatrice, always the first at a meal, looked at them, oh so tempting in the tub, and stuck her beak in. She pulled it back quickly, shook her head and went in again. Same thing!
Obviously, these creatures emit a don’t-eat-me stink that is really unappetizing, even to omnivorous Bloody Beatrice. So we drowned them in some soapy water.
