barn bully

Question
I have a walking horse, a new addition to my family.  I have two other horses.  They all like the barn this time of year, its very hot and it keeps the horse flys away.  My question is how to I keep the new horse from running the other two out of the barn, while he gets to stay in?
Thanks

Answer
Hi Linda.
  I've never had this problem. Two things come to mind: let your other horses take care of things. Horses will establish a natural "pecking order". When they've had enough, they will definetly put him in his place. My other thought is to put up some kind of a barricade, giving each horse a seperate area in the barn.
  Sorry I wasn't more help.
