My friend has had horses since she was teeny, and now that we're in college she has her set of "fixed" ways. I felt backed into a corner because the days I can't make it out to feed and clean his stall, she will come do it for me. I didn't want to deliberately do what she told me I shouldn't do and then her say she couldn't help me anymore. I doubt we're that immature at this age, but small things like that worry me... if she is helping me out on a daily basis, I do want to make her feel that her advice is being taken to heart.
Regardless, I let him out and I have never seen a horse buck so "over the top" in my life! He was very happy to be out and about. I figured he would be fine, horses are horses. I live in the deep south anyways, it doesn't get THAT cold here. 25F is very, very cold for Memphis.
