I jut got a rescue racehorse who raced for a couple of years, then ponied for a year. He is comng to my house to be a family horse for a friend of mine. He's a Thouroughbred,which I have very little experience with. I have 2 Arabians, a 24 year old gelding named Flame and a 1.5 year old colt named Mattie. I'm going to introduce the new guy to the others, but I'm worried because the new guy, Rocky, is so much bigger than my boys, and also because Flame is old and Mattie is young. Any suggestions for a smooth introduction? I don't know if Rocky has ever been pastured with other horses.
