I don't have much of an update as I was hit pretty hard with a respiratory bug for the last week & a half. Thankfully, I'm on the mend & back to work.
Drifter has had no problems being on his own since Stetson left. Today, he stood tied with the snaffle bit. He handled it being put in & removed well; he spent a short amount of time working his mouth initially, which is common. He also stood tied with the three mares at the barn for the first time. He had almost no interest in them from a stallion standpoint & continued to stand tied like a gentleman.
Tomorrow, he'll finally get his first ride outside & continue to transition into the snaffle bit.
