How do you feed calves with horses in pasture?

If you must feed them together make sure you provide the calves with a trough or feeder that the horses cannot get their feet or mouths into. This is for safety reasons as a horse could get it's leg trapped in a feeder and break it or ingest cattle feed which is unsuitable for horses in most cases. Horses may chase the calves off of hay or grain so you must keep an eye on them at all times when feeding them together, if a calf does not give way a horse may attack or even kill it. You could bring either the horses or the calve inside during feeding time or even build a 'feed pen' for the calves where they can go to eat and the horses cannot bother them.
