Start 'em off small and build up so that they're ready for 2 strand barb at 12 months.
Generally, I only want mine to jump fences etc at night if I can keep the lamp on the quarry,
otherwise, most times it's pontless
Day time, I expect them to go through, over, round, - the quickest way they can,
which in mid-stride is usually over
