To me, they seem to young and young of mind, I suppose horse mature at different rates, but for an animal that's going to live till it's 20/30+ why not wait a couple more years till they are fully mature?
Or is that the point, to get them while they are young and dis advantage to the big wide world??
I hope not to cause a big fight or a storm, just my thoughts :)
My friend recently bought a very nervous 2 y/o welsh section c and "broke it", when I met him he was hyper and bolted all over his paddock.. I didnt see it coming I guess haha
