When we moved here, I had a list, barn, fencing, shelters, etc., then we started fencing (63 acres) as the bill escalated, the barn shrunk and burst like a bubble. So we've lived without. Fortunately, we're in Northern CA and have a fairly mild climate. We have enough places to tuck horses away if need be, but not a true 'barn'. Now I'd actually prefer a covered arena over a barn. But no extra $$ sadly.
Plan your fence lines for ease of feeding/location of water. If I had to do-over, I would run electric piping with water pipes, even if you add it later at least it's there. Lights out in the pasture would be awesome. Water turn offs at each access point too. Gates wide enough for vehicles/tractors to get through, and walk through gates for you. Hot wire to keep them OFF permanent fencing. The fencing will last longer.
Have to have's
- a trailer for emergencies. We have a 2 horse (holds 4 minis), and our van (holds 1-4 depending on size.
- really good feeding cart. Hauling around a few bales of hay a day and salt blocks (200 lbs moved today), a great cart is worth it.
E-Z Haul Carts ours is 10 years old, we changed to solid rubber wheels and it's a work horse.
- automatic waterers or timers for horses out on pasture. I like to hand fill buckets for any that are confined (ie sick) to see how much they're drinking, but auto-water is wonderful
- gates you can open with open/close with one hand
- easy access hay storage for deliveries/feeding
- separate paddock/stall for quarantine and vet visits
You'll never have enough small/medium size pens. So if you plan on having 10 horses have 12+ pens! Different size ones too. One that's complete rubber matted (sick horses or colicy) on up.
