What a great idea Wimbles! I can see that may work if I get a door kicker again.
I have metal doors so if a horse bangs it reverberates all around! Day time mine stand behind chains so no noise. It also gives better ventilation and is quicker for people going in and out the stable.
I will not tollerate door banging and I am not spending out money on something to stop them when there is no need.
As someone said, a horse bangs to gain attention. If the attention he gets is not what he wanted then he will stop banging fast.
If a horse bangs the door then I go into attack mode and will charge to their stable and frighten the heck out of them by chasing them around the stable.
Some years ago I had a bad door banger in the form of a 14.2 pony. He would bang non stop if he fancied it.
Bad enough during the day but at night it was a bit much.
One night he had been bashing for about an hour. That was it. I was out of bed and ran to his stable picking up a broom on the way. I chased him around the stable and used the bristles of the broom on his belly - never physically hurt him but sire as heck frightened the door banging out of him. He never did it again.
He left my care and returned several years later. First feed time he started to bash the door, I called out his name and he ran to the back of the stable and never did it again whilst with me.
They want attention - give it to them but no in the way they want.
