PM Lockwood! She is a goat/llama/alpaca/donkey GENIUS! :)
And she's even nice!
In my limited experience with llamas, I love them! They definitely have a "different" sort of personality but it's a really great sort of personality. They also seem to have really long memories. The llamas I have contact with will let me pet them (I don't own them, I just fed them for a few years - they were originally feral and are owned by my neighbors) but I'm the only person who's ever apparently touched them...and they're 12 and 15years old.
Basically, they seem to be one of those creatures where they either love or hate you, but if they love you, they'll love you forever.
..not a genius by a long shot, but thanks Wallaby.
And again, Wallaby is right about the personality. They are generally more cautious and reserved than goats and a memory like an elephant. Not really affectionate, but they do like their necks and cheeks scratched.
Alpacas and llamas are nearly identical in terms of health care, feeding, and reproduction and many sites will cover both. They come from a family that is collectively called camelids, like SR said. This includes, camels, llamas, guanacos, alpacas, and vicunas.
It is very important to get the halter fit correct since llamas have long faces but very short nasal bones. The nose piece needs to sit very high on the face, just below the eyes. http://www.camelidynamics.com/
This one will give you a good idea of the basics. http://lostcreekllamas.com/basiccare.htm
LlamaNation dot com has a llama library under the community section, and if you click under llama breeders, you can do a zip code search to see who might be in your area. Most alpaca and llama people like to talk about them and don’t mind at all for people call/email with questions. It is also good to contact local llama owners because they can tell you what parasites are in your area and the best dewormers to use. For example, white tailed deer carry meningeal worm and can it can be transmitted to alpacas and llamas if you live in white tail deer areas. This has a strict dewormimg protocol that is different than other parasites.
From the pics, your boy looks to be a light wooled, or medium wooled llama. Depending on the individual animal, most light wooled llamas don’t need shearing, some medium wooled llamas do, and all heavy or suri coated llamas need yearly shearing. Once you figure out which he is and what your area (heat and humidity) dictate, it isn’t hard at all to shear a llama. Mine are heavy wooled and I’ve shorn them (and my alpacas) many times.
Also, more than likely the reason the ear tip is missing is from another llama. Males have wolf teeth that are razor sharp and when they fight/tussle with other males they will shred the ears like that. Most intact camelid males will do this not only to other intact males, but also to gelded males.
He's a nice looking boy and many llamas can be happy with a herd of goats or sheep. Hopefully he will fit in well with your animals and he is lucky you brought him home.
