well I didn't get MY first foal until age 16 and even then was VERY careful to choose the right foal for my personality... I needed a bold, cheeky, dominant type baby because I can be a bit overbearing and a timid foal would have been entirely wrong for me at that time.
Now, age 18, I've since sold her [she's too small - will be lucky to make 14.2, and I'm a bit tall on my 15.1 gelding], and taken on a 2yo, very flighty TB. Maybe it wasn't such a great idea going straight from first ever young horse to a 2yo red TB filly with issues, but so far it's working out ok other than her incessant health issues... one thing after another! I think I learned enough about training methods from my first youngster that I don't have to figure out how to handle a flighty horse AND how to train at the same time, and there's a certain degree of instinctivity to it because I've basically been around horses my whole life.
As an outsider looking in on a number of my friends, there are friends who I would never sell ANY horse to let alone a foal, there are friends who I'd give a horse to in a heartbeat [no charge, any age] because I know they'll train, handle and care for it properly, and there are friends who I'm considering BEGGING to help me out with my current youngster. I'm seriously thinking I might talk to my boss about a little hurdle I'm facing, at the very least.
Guess what I'm trying to say is people will do what they will do, if you don't agree don't enable/help them... but do encourage education and most importantly that they GET HELP. Foals are very cute, and one of these days I will breed one [or a few?] of my own, definitely one to keep and possibly a few to sell... but I have my mother with her 25+ years of experience, my boss, 3 very experienced horsey friends... the list goes on. I have a VERY good support network and this is the ONLY reason I have young horses at all. If I didn't have my support network I would stick with the older schoolmasters.
