Alot depends on where you live. Here in NY it is a bit less expensive as hay is affordable. BUT that said, one mini may get very lonesome. You may want to consider 2 or get a goat for company. One mini won't eat much, nor will 2 seeing as this is what I have I'll share what keeping 2 costs me.
Now that it is cold they are fed their feed (Strategy) in the morning about 7:30 and I split a flake of hay between them in their stall. Now they share a 10x20 but before they each had a 10x10, then about 9am I go let them out. They always have some grass hay in the shed to munch all day but it is usually the extra that falls to the floor of the hay room. In "really cold" weather I will go out about 12-1pm and shake out another flake. Then at around 5pm they come in for some feed and I split a small flake for them in their stalls, then I go back out at around 10pm to be sure everyone is ok and give them each more hay, the amt will vary on how cold it is and turn out the lights. I have been known if it is near 0 to put a flake in each corner for the long nite. I leave nite lights and a radio on all nite in the barn.
SO...feed...a 50 lb bag of Strategy costs me $9.56 and I use 1 bag a month $9.56x12 mos=$114.72
Hay a bale lasts me 2/3 days depending on the weather...hay in the NY/Pa area is about $2 a bale, I bought 150 bales that = $300 for a years hay.
Worming...every 6 wks for a yearling, every 8 for an adult (just my way) per year, for 1 or 2 minis = 4 tubes at an average price of $7 tube= $28 for yearly worming
Required shots....costs will depend on your vet call which is anywheres from $25 to $100...mine is $35 just to come here, the shots are then $20 for vaccines and $15 for Rabies. Once yearly for me w/ 2 minis=around $115
Note....one should "try to have an extra bit of money for those horsie emergencies. Stick your change in a jar..put aside $5/wk anything OR ask your vet how you would go about dealing with an emergency and the paying for it. having a plan is the best.
Farrier....every 8 wks, costs vary from $15 to $50...the farrier I use now charges $25/horse every 8 wks. I have paid as much as $30 and as little as $15/horse. So average it out and multiply it by 6.
Now comes the extras.....feed pans, water buckets, salt/mineral blacks, a nice halter, a safe lead line, good safe fencing, good warm shelter, bedding....and so on.
Good luck with your new addition(s)
: Like you....many years ago I did my homework before buying and I applaud you for this. That was before I had a computer and I had to rely on the kindness of folks on the phone and sending pictures thru the mail! :new_shocked: Be sure you know all you can then realize they are horses big or small..horses they are.
Oh tho I have never had a gelding done they cost here about $150.
