I don’t agree with it. The only time I’ve ever even been around a stallion is when I interviewed to volunteer at a barn and they boarded a stallion. He was kept in a stall 24/7, all parts of the door closed and enclosed sides.
I felt quite sorry for him. I never went back, they said you had to watch him or he would attack and I didn’t feel safe. I had even less experience than I do now.
I remember thinking he might not be as unhappy if he got to live like a horse.
