I also had a young horse for a bit. I bought her at 3 weeks old and she stayed with her breeder until 18 months. I started having doubts about the whole thing a few months in, but kept with it until she was 2 1/2, when I came to the conclusion that we just didn’t mesh well. Sold her back to her breeder and she has a good home now.
It turned out for the best, I guess, because there is no way I could afford 2 now, given how much board has gone up. So I would have had to sell her or euthanize the “worthless” Feronia.
