Stable issues

I would take him off all feed except grass/hay based feeds and see if the behaviour changes. Many horses react badly to almost every ingredient in commercial feeds. The fact that a particular feed has been recommended by a nutritionist means absolutely nothing to the horse.
There was a thread not so long ago about a rearer, it now seems that it could well have been alfalfa that was the cause of the dangerous behaviour, as many of us thought. The last I heard about that horse it was doing well with no alfalfa in the diet.

Pearlsasinger is right about food. One of mine is an absolute saint of a schoolmistress who I bought to give me confidence after a serious accident. She has never put a foot wrong apart from one day when some kids at the yard were feeding her homemade treats. I didn't worry as the mother assured me that they had followed a safe recipe, and I know how sensible she is, but that day she behaved like a different horse. Spinning at the mounting block, proper bucks, and all of this from a horse who I very often ride in fast canter in a headcollar.

My horse was the same at my last yard. He was in a normal stable but could not see his neighbours unless they had their heads out of the doors. If anyone in the yard moved before him he went mental. The yard had the same routine so everyone got out at the same time but this didn’t matter he -had- to be first or he would be a nightmare. This got better when he had a haynet in as he was hungry (similar situation to you, very low ranking horse came very very skinny) he was unable to enter the stable at all in summer time without a melt down and was a handful on the yard too which made summer riding a chore.

he never got any better in the two years I was there. I moved yards and he now has a barn type stable and he literally walked in and sighed with relief and hasn’t had a single episode of this behaviour. He can be left in to last, left in entirely alone and doesn’t really care about much in life.

I didn’t realise what a stress it was until I no longer had to think 10 steps ahead and guess every other horses movements before they happened.

I think for you plan 1 should be leaving a bag of hay at the door so the first one there can fire it over and see if hunger is a cause for him wanting out so badly (it was for mine)

if that doesn’t help have a look at other yards. Trust me we spend too much money to be stressed out every day because something isn’t working.
