Idk about all you guys but I just got my first horse in december 2008 so basically a year an 3 months ago? I as completely horse crazy. But I had never ridden in my life and my horse had never been ridden. I broke her and she taught me. Now we have 6 horses where we live but only 4 are ours. I had my first foal a little over a week ago. And he is a dream come true! I did everything backwards but so far my luck as been good enough!
As for your guys's feeding schedule lol you guys are crazy! I don't feed twice a day. The horses get fed once. And the horse who was pregnant and just had the baby gets fed twice. I fed her around 6:30-8 anywhere in there and she got 4 flakes of hay. And then all of the horses(momma horse included!) get fed at 3-8pm and they get 4 quarts of all grain. And get 1 square bale to share(momma gets 4 more flakes to herself). And they are healthy as can be.
Things my way have worked for me. But all horses are different and all of mine seem to be easy keepers so this works well for me.
