I agree 100% with this post. We need to feed horses the way they were meant to be fed. Freedom is a worrier. No doubt he came off the track with ulcers. He lives out 24/7, gets free choice grass hay, very low starch concentrate, and soaked alfalfa/timothy cubes (the alfalfa is a good buffering agent for stomach acids). This approach has gone miles toward keeping him comfortable.
In fact all our horses get unlimited turn out and pretty much as much hay as they will eat. I am very lucky to be in a place where 24/7 turnout is possible. While there certainly are horses that like the comfort of their stall, most seem content braving the elements and having enough space to chill.
