you're exactly right.....
We will give the wool to the local people who spin it for their shearing of the Llamas in early summer. Llamas can suffer from the heat as you might guess, so shearing them once or twice a year is important. You also have to set-up a fan to blow, when they get to hot they get in front of the fan.
And you're exactly right about proper socialization of Llamas. It a problem with the males. They need to understand from early on that the human is the master and they are the follower. Otherwise they want to compete with you. This only goes for the males though, they're the ones that can be aggressive, females are typically very gentle. The males are geldered though, and this can fix a lot of their problems.
Llamas will click, or cluck, when something is bothering them, like a new person they don't know getting around their baby. They like to come up and smell you first, etc. Spitting is a defense mechanism as well as a way to establish the pecking order in the herd. Very few Llamas will spit on people, but if they're mistreated or bothered by people in the past they are more likely to. The two girls we are getting are gentle and shouldn't behave this way at all. And Llamas are very affectionate, much like dogs. When they get attached to you they will do about anything to help or save you. They'll get between you and stray dogs to protect you, one woman said she was crossing a fast running stream, she started slipping and hollered for her husbands help, her Llama, which was still on the shore, went in downstream of her and got against her and helped her across. She says now that everytime she come to water, the Llama moves downstream of her and assist her across the water (and Llamas normally don't like water much).
So they can be quite unique.
