I'm getting alpacas for a school project. Yes, I've done my research. I know about common diseases and dietary needs. BUT... I don't know how to pick out an alpaca. I want show-quality animals, so I need to know what too look for when I pick some out. I do plan on breeding. Can anyone tell me more about the specifics? Hair length and color (I don't think that matters, does it?), feet, legs, body proportions...? Thanks so much for any answers.
