And just double-checking, for a green owner it is a stupid idea to get an unbroken horse and get it professionally started, right?
I see nothing wrong with this as long as you work under the trainer yourself. It depends on the horse, The right one will come to you.
All my horses came to me young. I got them as weanlings or yearlings and then at 2 years they were sent to the trainer to be started. Brought home after 30 days of 5-6 training sessions a week, we were very pleased. A year later we sent them back for a refresher 30 days and I've never had any issues with my horses.
My first horse was a yearling. Second horse was a weanling. I worked under a wonderful trainer and a great horse mentor, my aunt.
I would actually prefer to get an unbroken horse, spend lots of time on the ground with him, get the manners a horse should have down pat, send em to a trainer, work with the trainer and take lessons. That way, I'm not buying someone else's problems and mistakes.
It's completely up to you. Like I said, you'll meet the right horse, and you'll know. Whether it's young or older. :)
