The phone call was to tell us that the heifers were now in a field right next to his farm and he'd be happy to help us get them. As soon as we were in sight of them our "girls" started mooing, thankful to see their friends. They followed us straight to his corral where we loaded them up and took them to the barn until we could find and fix the hole in the fence of their field. Thanks to our neighbor's help, these were truly round up ready calves.
Where did they get out? Storms blew down a tall tree in a corner of the fence. The tree fell at an angle and managed to take down both sides!
