My horse will not turn to go away from the barn?

Firstly, understand why.

Horses are prey animals. They feel most comfortable in a herd environment. Leaving that security makes them wary and many horses will simply become aggressive and pushy in their desire to return there. If not corrected the right way, she will continue doing this. Emphasis on the "right way." Clinton Anderson has great tips for this sort of thing.

And you're right, she does associate the barn with rest. Do it on the ground first. Try making her work hard around the barn, even in the pasture with all her horse friends. Make her work hard there (hard! She should be a little out of breath), then trot her away from the barn a hundred feet and let her rest for 5 minutes or so. Do the same thing again, but this time lead her a little further away to let her rest. She'll start understanding pretty quickly that "Oh! If I go too near the barn, my owner will make me work hard and make me tired. I'd rather be far away and rest."

Also try just doing simple groundwork exercises. I'm sorry, but it doesn't sound like your horse has a whole lot of respect for you. Misbehaving is a clear sign of disrespect. The only two reasons a horse acts up are fear and disrespect for the handler. Often her behaviour is a just a symptom of a cause - get to the root of the problem and other problems will magically disappear. Work on getting her feet to move when you want them to move and at the speed you want them to move.

There is really a lot to explain and I can't do it all, so I'll recommend a horse training book that really helped me. A lot. It's called Gaining Respect and Control for English and Western Riders, by Clinton Anderson. Do these exercises the right way and you'll be amazed at the change.

These are some of the exercises he goes over. Believe me, you may think you know how to do all these, no problem, but read that book and you'll understand much better, just like I did. It's worth every cent. I think he actually addresses barn sourness in the book, too.

1) Backing up.

2) Disengaging hindquarters and forequarters.

3) Flexing.

4) Lungeing for Respect

5) Circle Driving.

6) Sidepassing.

You probably know a lot of this, but please trust me with the book. You won't regret it if you give it a chance!!

Give her a reason to want to go that way. If you do not fix problem soon she will start to rear to have her way.

See if you could find someone who would let you keep her at their place overnight or just for a few hours that would be a long ride from your barn. Let her miss two meals, Saddle her up and make the horse go there where you would have some hay, grain and rest waiting for her leave her there over night or a few hours. Make her walk quietly the last block or two on the way to your barn then do not put her in her stall tie her somewhere with her head up and leave her there a few hours or just ride the pi s out of her before you put her up.

That is the way I fixed the worst rearer/balker I have ever had to re train for someone.. The second day she lined out at a long trot and wanted to go.

I had a horse that was the same. You'd try to go out and he'd turn around and try running home. I tried spinning circles but he soon learned to just not turn.

So I ended up letting him turn for home and then making him back up. Its a lot easier to back a horse up then make them go forward. I'd make him back up a few steps then ask him to turn around. If he didn't do it then we backed up again. Pretty soon turning for home just meant he had to walk backwards. We did this for an 1/8th of a mile once before he realized that trying to turn for home was no good.

Yes, when she tries to go back, take her and then work the daylights out of her. Then immediately take her away down the trail and let her rest. Repeat whenever she asks to go back. The first time or two bring her back when it is your decision fairly soon, but each time the time out should increase.
