Am I wrong? I still want it filled it, but hubby insists his **brother said it couldn't hurt a horse**.
His brother's expertise with horses? An old pony (20+ years old) someone gave them, and it got out of the fencing he put up for it. It got loose on their 130 acres, in the winter, and he figured it would just come home. It (or rather, what was left of it) was found that spring, dead.
No, they never rode the pony, nor spent time with it, nor did anything with it. Just put it in a fenced in area next to a pond for water. The pony was given to them in the late fall, and they only had a month or two before it got out.
