ok so heres my dream barn
It would have 10 stalls all 24x24. Heated for winter and cooled in summer. Lighting setup so that the horses never get winter coats :) each horse would have a one way door that allows them access to the paddocks. (this sounds waaaay out there but it looks good in my head lol) all stables have timed fly sprays and air fresheners D:
For feeding you fill all these compartments with the the bags of feed and enter in a stall number and a recipe for that horses feed. It mixes the feed and delivers it through a pipe directly into the horses feed bowl
hay would be kept in bales above each stable and when required, a flake is dropped down into the stable (oh don't worry, my imagination has way more to go yet lol).
The padding on the barn floors would soak urine through them and dispose of it via a neat little plumbing system under the ground. In each corner there would be a trap door and all poop can be easily shoveled into through the floor and out through the same system that the pee would use :)
All stall doors would be automatic with a button both inside and outside the stall for easy and quick access. No more trying to hold feed buckets and open the doors
My tack room would be awesome too :) I would have a hook and a place for everything and I would have a Tack Wash station. This is another idea I've had that would make cleaning tack easier. Its like one of those car washes that you see at service (gas) stations with the big floppy things that wash the car. Well, you put your bridle in this contraption and the brushes slowly and gently clean your tack until it sparkles.
I can't think of anything imaginative to clean the paddocks so the horses can just wear nappies (diapers).
Then I would have an indoor arena branching off to an indoor showjumping area which has direct access to the 40 jump cross country course set up around the property :) after all that, the horses and me can cool down in the onsite pool especially designed for both horse and human use ;)
