Calves have their budding horns seared off, chicks have the tips of their sensitive beaks cut off, and piglets have their teeth clipped – all without anaesthetic. Dairy cows may have ‘extra’ teats snipped off so they fit the milking machines better, and sheep may have the skin around their buttocks painfully removed to prevent parasites. These practices are not just legal, but common, and occur in free-range and cage-free farms as well as factory farms.
