Sorry you had to sell one of your babies...that's always hard.
I remember one place I was boarding at, the horses got out, and two of them WOULD NOT get caught...we spent hours trying to catch them. My boy was caught pretty much as soon as he saw me, so I hopped up on him bareback and started trying to atleast herd the other two away from the road, and back toward home! We finally caught them, and the BO started leading one of them home; she tried to pony her other horse, but couldn't get him to stay on one side, or to stay with her. So she tied him up, and went to bring her other one home. I didn't want to really stay out there anymore cause it was a cold rainy type day, so I grabbed that naughty horse up, and he learned how to pony properly. I had a really calm willing horse though, so that may have made a difference; the BO horse that she was riding was a bit difficult at that point, from being loose and wound up! Lol!
