I have never tryed to give my horses silverbeet, but wondered if there would be some benefit to it. As it's high in iron, would that be of benefit? I know my birds love a few leaves, and the ducks and chook inhale the stuff, so why not horses.....I will hold off until I get some feed back. Very interested to know if anyone has had good or bad experiences. We have a garden full of the stuff, and theres only so much you can eat, and palm off onto others (without appering too rude) I'd love your feed back.
