I used to ride horses when I was younger, but haven't been around them in 6+ years. Nowadays I'm just a dog person!
I'm currently casually breeding unicorns. Horses in the "sale barn" are for sale, they are mostly horses that are left over from my old breeding projects. Most are decent GP/IBS but very far behind the current top horses.
I look out for high (20K+) GP draft horses with no coverings left in the sales; I use these horses for my EC.
My favorites:
Phoenix: My first homebred rosette winner
Mello: Nice Perch unicorn that I have no studs for
Wikaila +
Etrian: My favorites divines because they're from that game that Ubisoft shut down for some reason
