Purchasing First Horse - Young or Old?
Hello, a little background about me :
I'm in a family of 5 including 2 teenagers, myself (in college), mom, and stepdad. Teenagers and stepdad are fairly tall (~5 1/2' teens, 7' stepdad) and stepdad is fairly heavy due to such (300-350?), teens are about 130-150, I'm 110 and 5 1/2', mom is about 5' and 150 or so. We're looking to get our first horse, the only real person with any knowledge about horses is me but I don't know all that much (I can properly saddle, use tack, lead, etc but haven't actually ridden over 50 hours). We already have 9 goats, young and old male and female, all disbudded with the exception of one that wasn't done right, the whether but he's very gentle. We have 10 acres, about 1/3 of that is fenced off from the goats, and another unfenced 10 acres we don't really do much with. Plenty of forage, a single large barn with 3 stalls (one milking, one for goats, and one unused).
We're planning on getting our first horse but we've received mixed ideas.
First idea is as follows :
1. Get young horse, they're not too hard to train, that ways they'll get used to goats.
2. Get old horse that is used to goats and already trained.
3. Seperate both.
So far everyone has been hooked on the first option. They have the idea we need a 2 year old colt that is atleast 15 hands tall and I'm pretty much going to do all the work. I've had experience AROUND training sessions but never actually trained one. I'm fairly patient, but honestly I'd rather be out riding with an already trained horse. For some reason everyone thinks that we only need one family horse for all 5 of us to ride even though we're all VERY different.
Personally I think the better option is to slowly adjust an already trained horse to the goats, get a youngun, and use the older one as a standard for the young one to grow up next to, but chances are we're just going to get one horse because no one listens to me and I'm not the one paying.
We would prefer a horse for trail riding which is why mustangs have been called into question. Obviously there are plenty of other good breeds but mustangs are being considered (they already turned down a 14.2H 4y colt that I believe was greenbroke for $400, but it was in CO...). They think the taller the better but I know a stockier horse will be able to do better with a stockier person. I personally want an endurance horse, but I wouldn't know if it would be able to be a good fit for our entire family.
So the question is, which is the best route to take in our situation and what horse should we be looking for? There are horse auctions near us every month, as well as people near and far selling them all the time. I'd prefer not to get too old a horse just because of health issues they may have.
