CUT = compact utility tractor. the smallest of which is a SCUT (sub compact ...) such as a kubota BX series looks like a rideing lawnmower with a front end loader and rear 3pt hitch
Some bulk places will bag your order of 2K lbs for you at an additional fee ($1 a bag or some such) even with the bagging fee it can still be less than "store bought" feed. plus you can customize your blend of feed per how you want to feed your girls. You can then palatalize the bags to 10 or so bags per pallet which you can then tractor in and stack in your barn.
with our 24 chickens we go through about a 50lb bag a week this time of year (nothing to forage out in the yard, we free range) which is why i say most people move to bulk around 40 or more chickens due to the volume of feed you go through especially in winter when there is little to nothing to forage.
