I have a 4 month old male llama he will be available mid December to offer great protection for your herd. He has been around other llamas, goats, and dogs. Have not seen any signs of aggression.
My neighbor has a 6-7 year old male llama that has proven to breed. They are looking to downsize. Been around other llamas, alpacas, and goats. No signs of aggression towards people. Last pic is of the 6-7yr old.
$700 for young male.
