Blinkers? Sharp spooky horse

looks lame behind in the vid going up the long side from behind at around the minute mark.

My boy was exactly like yours, very sharp and spooky especially in the wind. My mare also headshakes as an evasion, with both i turn them both in a tight circle - get their attention back on me and they soon tire of it.

Would check her behind first though.
 
Wow OP, you've had some really good advice on here.

The only advice I can offer is to forget about blinkers and instead get yourself a big fat sheepskin(fatter the better) and wrap her noseband in it. Also, she looks unhappy with her head so I'd hazard a guess she's a real complainer if shes in the slightest bit uncomfortable? Try a Micklem bridle and check her tack, including her girth. It's amazing just how badly some horses will go if something is just not right.
