I have 6 horses on my property, will be bringing another home soon, and am selling one. Four are horses and 3 are minis.
I use SafeChoice and only the big horses get fed grain. I go through 9lbs a day, a bag every 5 days. A bag I get for $12. I spend around $72 on grain a month. Hay....The best quality around here for the least amount of money is $3, we go through a bale and a half a day, 45 bales a month, $135 a month on hay. So $207 a month on feed. $2484 a year.
Shavings are $4 a bag, we have three stalls, we use 3 bags a week. $48 a month or so on shavings. Around $576 a year.
Farrier....We pick up someone in Amish Country who does a great job for cheap. Between everyone, we spend I think $70 every 6 weeks.
Add to that vet, fencing repairs, lessons, tack, supplies, pasture and arena dirt, time, energy, and exhaustion, and you have a heck of a lost spent on our equine friends!
