Ok now you have decided to join the alpaca world…congratulations!
The biggest thing alpacas have to teach us is patience nothing happens quickly with them and when you go to purchase them you should also take your time. Do research and when you think you have done enough do twice as much as you though was enough and your half way there.
You should also educate your self to fibre, bloodlines, conformation, health, birthing, feeding and maintenance of the alpacas. Visit as many farms as you can go to a show and maybe help out on shearing day at a local farm. Try and find a mentor to help you and teach you preferably some that doesn’t have an alpaca to sell you.
