We feed orchard grass or orchard alfalfa here in S California. Every horse that has been on bermuda has had colic episodes so we don't trust it. It is the first question asked at the equine clinic when they get a horse in...Is this horse eating bermuda grass. Anywhoot...some horses take awhile to acquire a taste for it as it does take them a bit longer to eat it. My horse eats from a hay net so I don't know about free feeding it.
