I have 3 llamas (2 females, 1 male) and 2 alpacas (both males). One of the female llamas is new, well since May, and I tried to use the wand to separate a few of them and she flipped out when I brought it in and ran out of the barn. Anytime I have it she looks frightened of it. It doesn't work very well when she is scared of it, what do I do?
