What I like to see is a barn owner who follows the feed schedule the owner sets, and doesn't adjust it how they see fit. i have no problem buying my own special feed if my horse eats something the farm dosen't feed, but I get a little irate when I find out they are feeding my horse a scoop of sweet feed with his normal ration, and enough hay that he has enough to swim in for 3 days. My horse can be a bit of a hot head, and defiantly doesn't need the extra sugar from sweet feed.I expect water buckets to be plenty low enough that my guy doesn't have to strain to reach it. Mini safe fencing and turnout away from other horses. A dry lot for show season when I want him kept off of grass, and of course, a round pen, preferably with sand footing. Electricity and running water to the barn, its a huge plus if it has warm water. Also, If I live more than 10-15 mins from the barn I need access to a restroom or porta potty.
Right now I pay $50 a month for full care board on a mini gelding at a big horse barn that has an indoor arena, bathroom, tack room, outdoor round pen, however no real turnout for Midas. He gets turned out in a big indoor arena, and sometimes out in the round pen. I was looking into moving him either home in the spring, or to a persons farm that had emailed me (I had a posting on my local craigslist, but when I sold my other computer it wiped out even my web mail email, and I lost contact with them. The situation sounded perfect too, so much for my luck)
If I don't get him moved home by this spring, i'm going to talk to my barn owner and see if she will let me fence in a small dry lot area for Midas, and whatever other horse I get to show this year. I'm about positive she will say yes, I just need to figure out what I am doing for sure before I talk to her about it.
