Good luck with your donkey! I loved my little guy. It is easier to work with them once they are separated from their pals. Otherwise they tune you out in favor of the herd. Just working in a quiet place, with a quiet, sensible manner went a long ways towards settling my guy down. Stopped kicking once the fear left. A small help was to gently and slowly massage the tip of one of his ears with my thumb and first two fingers.
