When we were considering a llama as a sheep guardian a decade ago, people advised to get one llama, not two.
A single llama will bond with the sheep; two llamas will bond with each other.
For a decade now, Llambert the Llama has watched over the barnyard and pastures. He's learned who belongs and who doesn't. He raises neither a lip nor twitches an ear when he sees our dogs in the yard, but a visitor's dog sends him into alert mode.
And, he's learned to tolerate the Buckeye chickens who roam the farm and think nothing of hopping on his back.
Or maybe they've come to an agreement: a soft, warm roost in exchange for a back massage.
