See if there is a pasture that is either a dry lot, like Peggy suggested, or a pasture that has little grass in it.
When we moved Gem and Vega, their "stall" when they weren't out grazing in the bigger pasture, was a nice sized pasture that was already eaten and was half dirt, half grass (but like I said it was already eaten). They would go out for 2 hours and would gradually be worked up. But when Gem coliced, we got a grazing muzzle for him so he could be out with Vega but wouldn't be able to eat a lot of grass.
As for you question about them being hot or having more energy, I found that Vega (My "hot" mare) has calmed down considerably and has become more laid back. I feel that when horses have the chance to roam and do whatever they want expel off their energy more so than horses that don't have the room (Like a dog kenneled all day, as opposed to a dog that is allowed to have run of the house)
