Sorry if this is the wrong place to post this xP
I recently got a new gelding and he is very well behaved undersaddle but the other day when it was a little sprinkly outside I decided to let him and my mare go out in the pasture just to have some free space to run and roll around while I mucked their stalls. Well my mare was having a blast and was enjoying every second of it, but well, he wasn't! He ran straight to the fence to where the stalls were and would not stop pacing and weaving along it! It even seemed like he was thinking about trying to jump over the fence just to get to his stall! I couldn't shoo him away from the fence he would just almost run me over and keep pacing/weaving and it was starting to get dangerous so I just had to give up and put him in his stall, however when I started mucking his stall I put him outside of the stall so I had room to get rid of all of the puddles (it was raining heavily earlier that day) and he kind of wandered around but not much, and was bullying the other horses that were in their stalls for food and he started pacing for his stall again. I finished the stall and he was happy again but when I gave him some pellets he would pin his ears at me when he was eating like he was afraid I was going to steal his pellets that I gave him. He also seems to get really ansy when I tie him to ride, but he calms a bit when I put the saddle on. So what can I do to stop this? I want him to enjoy being free in a pasture like the other horses, not freak out! Please help!
