Some llamas can be caught readily but most like to play a game. 1st you need to get them in a restricted area but they quickly learn that going into a corral means you're going to catch them and they won't go in. I have a small pasture, maybe 1/8 acre, between 2 larger pastures with a gate at each end. I just close one gate and they'll run right in. When catching them, they'll run back and forth 3 or 4 times then they'll get in a corner and stand while I halter them. It's just a game they play.
