In most cultures, shepherds occupy the lower rungs of society 's ladder.
Metal rungs set in one side of the shaft were the obvious means of access.
They can hop, stand on one foot, and negotiate the rungs of a jungle gym.
They are arranged so they line up like ladder rungs, one above the other spatially when worn.
Ladders are not a good idea for young budgies, as they can get stuck between the rungs.
