She gets 3 lbs 2x a day, in the morning it gets stolen. At night, she is put in the round pen to eat and gets all of it. I am not sure what to do about that. She is not up to an ideal weight yet, so I put her on purina junior and strategy and she is not getting it sometimes =/
I do everything with her in the round pen. Groom, tie, saddle, work. She has a phobia of barns. We will work on it soon though.
So what you're saying is she isn't pulled out to give the grain instead she gets it in a field?
I would try to avoid that.. if possible. That would sour even the sweetest of horses quickly.
Also try and take your horse out for a nice hang out groom then graze session. Then do a little bit of "work" and then go an spend some time bonding with your horse. Maybe even think about giving her the grain not when everyone else gets it, but before (or after) you ride/work with her.
Man.. my horse used to be in a paddock with 30 (I kid you not) other horses in less than 4 acres. It was insane. And he'd maybe get 2 flakes of hay PER day.. it was horrendous. So I started feeding him hay before AND after we rode, and gave him grain once or twice a day. He started to come greet me at the gate even when he was turned out on an additional 6 acres (so 10 in total) and we bonded a lot better.. no sassy-ness or anything like that. And he's the kind of horse who will gallop away like a jerk than get caught. So it was a huge step.
Now if you are approaching your horse and she turns and walks away or turns her butt to you, DRIVE HER AWAY make it work!) When she looks back to you, stop moving and release the pressure. Give her a few seconds.. if she turns around, great! If not and she continues walking.. drive her off!
Until she stops walking away from you and faces you or even stops sideways, release pressure and approach without looking at her. Look at the ground, appear small and have a soft aura. Maybe bring a little treat so when you DO get to her, and halter her and stuff, she gets a cookie.
I hope that helps. It's frustrating when they blow you off!
