The barn looks great, like the tack room. Glad to see that the horses have found a great home. I am like you, I ride once in a while, but really just like looking out in the pasture and seeing them. Our horses are very calm and friendly, they love attention. Enjoy brushing on them and seeing how much they enjoy it. We have 3 and they are quite "healthy" looking, meaning they eat well. The wife, daughters and grandkids ride them and they have been trail riding horses for several years. The comments here regarding feed are very true, a horse will eat itself to death. We give them grain twice a day, half oats and half sweet feed, but only about the equivalent of 2 or 3 big manly handfuls. They get about 2 flakes of grass/alfalfa hay in their stall at night when we put them up and we have feeders in the "sacrifice" lot that we put a bale of hay in when they are put out for the day. If the pasture is in good shape and letting them in it won't tear it up we do not give them hay because they will be eating the grass all day. We never leave them out on the pasture at night because we have a very rich pasture and they would end up sick. They primarily need two things; access to clean water and forage, feed is great, but if they have good pasture they can get by without it.
We will be moving this year from our 4 acres to 15 acres, building a new house and horse barn and giving them a 5 acre pasture compared to about 1.5 acre they have now. Can't wait to see how happy they will be and there will be a lot more room to ride without having to leave the property.
