I had a half of an over ripe watermelon and put it out with the horse and sheep thinking the horse wouldn't like it but the sheep would. I was wrong, the sheep didn't care for it but the horse loved it. She started eating the whole thing. I was worried that half a watermelon would be too much so I took it away from her after she had eaten half of it. Does anyone know how much is safe to let her eat. She'd have eaten a whole one if I let her.
