I keep the three of my horses on my grandfathers farm. It's a pretty old farm, belonged to my dads' great grandparents. The horse barn is an old draft run in shed that had been converted into a barn with three stalls and enough for some stack by my aunt many years ago when she was keeping her horses there. Since then, the chinking between the logs has all fallen out, leaving the barn freezing cold during the winter and very hot in the summer. Storing our hay is also very difficult, it's constantly being tossed through a hole between it and the barn beside it. My parents and I have been discussing how much easier it would be to turn the old dairy barn into a stable, it's bigger, warmer in the winter, cool in the summer, and has a water pump inside, and the loft if big enough to store all of our hay.
The barn already has a few small box stalls for when the pregnant cows are birthing, but I don't think they'd be big enough to for the horses. In which case, the entire barn would have to be gutted. It also has a manure gutter in it, along with all of the stanchions. I would love some tips and design ideas!!
Unfortunately I don't have any pictures of the barn right now, I'll get some the next time I'm out. For now, just imagine an old, dusty, dairy barn with a few box stalls in the back!
