Horse acting up

Hello,



So I’ve had my boy 3 months, he moved from the homes he’d lived in most of his life to a field then to a yard. Currently at the yard and we’ve had a few issues but then seemed to sort it out and he was next to 2 mares and waiting for another gelding to join him. The gelding joined and he became very dominant and bullied the gelding, never been like this before. Now every time hesnout in the field he gets out or causes havoc. Crashes through, lifts it up, goes through the middle or jumps the electric fence. I thought it was boredom but he’s ridden every other day and we had a very tiring jumping lesson and he still did it and yesterday was chasing one of the mares. I just don’t know what to do



please help



Thanks !



I didn't find the right solution from the internet.
