I transport mine in custom made show box transporters, designed to be dark and calming, small as to restrict movement with smooth sides so it doesn't mess up their feathers, it must have a slide opening preferably in the top, no places for food or water as you don't need this and it makes a mess. Try and make the boxes where they hold no more than 4 banty or 2 LF holes for easier carrying and loading, plus when cooping in, line them with plenty of clean large chunk shavings. If you notice almost all show folks use these type show boxes, mainly because they work and are the best choice.
