Any ideas?
She will go out, reach something scary then try and spin for home. Sometimes it's something she's seen a million times or a noise etc. Once she's silly then she's silly for the rest of the ride/walk. She never seems to settle again. Sometimes I get 5 steps of the yard, sometimes a mile. It's not the same spot every time.
Once we turn for home she starts jogging and refusing to stand, she will try and spin in the home direction. Not all of my rides are circular so sometimes I have to turn back and every time she is silly. She's also silly when passing horses on the way back to the farm, whinnying and trying to jog to them.
If she sees another horse and rider hacking im stuck with them 
She often plants and won't move at all, or backs up and bucks refusing to go forwards.
I've tried sitting it out,the nicely nicely approach and also getting cross but nothing really works.
I've also tried walking her out in hand however she is strong and bargy and I don't feel I'm in control. She long reins but again she won't budge.
She hacks in company fine with no issues.
Can anyone give me any tips to get her going out alone. I really don't want to keep a horse that won't hack as it is a pain to find hacking partners?
I have lessons but obviously this never presents itself in the school and she is always well behaved in there.
