It's good that you are enjoying your alpaca and it sounds like he has found a loving home.
However there is a tremendous amount of misinformation posted on this thread about alpacas. Here are a few basic facts:
1) Alpacas are herd animals and require the company of other alpacas to be comfortable. Stress is a huge issue for alpacas, and they will not show signs until it is too late. Not having other alpacas around is a big stresser. Goats or sheep are not acceptable substitutes. Nor are horses. A kick from a horse can kill an alpaca. If you are interested in owning alpacas as pets and to spin some of your own fiber you can obtain good quality gelded males for free.
2) In Indiana you live in meningeal worm country. Your alpaca should be vaccinated every 30 days with Ivomec (not Ivomec Plus), subcutaneously (under the skin), at a rate of 1cc/100 lbs of body weight. Meningeal worm will not become resistant to Ivomec because the alpaca is a dead end host - that is the worm will never leave the alpaca's body to reproduce - but it will kill the alpaca in a slow and painful manner.
3) A good quality low protein hay is required. Orchard grass is ideal. No rye grass - they get staggers like sheep, and not too much clover either. They love alfalfa but it has way too much protein and will eventually kill them. Supplemental feed is not necessary, but if you do want to feed some limit it to 1/2 cup per day or less. Blue Seal, Mazuri, and Poulin all make a mix for camelids.
4) Free choice minerals should be made available. No copper, but they require higher selenium. Stillwater Minerals 104 is a good mix and is available on line. It's okay to wait and get it delivered. He'll be fine.
5) Alpacas MUST be sheared every year in the spring. Mid May would be a good time in Indiana. They are very susceptible to heat stress if they are not sheared. Difficult to tell from the picture but if he was sheared this past spring he should only have a couple of inches of fiber by now. The neck should be sheared as well.
6) Toenails must be trimmed. Kind of tricky but not too bad once you get the hang of it. Front teeth may need to be trimmed as well, and the fighting teeth definitely need to be trimmed. A gelded male is a happy male and much easier to handle.
7) Your guy (nice dark brown color BTW) appears to be missing some fiber on his lower legs. Could be a bunch of things but you might want to try some Nu-Stock - available on line. Inexpensive and effective for a wide range of skin issues. Below is a picture of good leg coverage.
8) Parasites. Yep, they got 'em. The most common parasites in alpacas are coccidia, nematodirus, strongyles, tapeworm, and barber pole worm. They can also get caseous lymphaditis from goats, and it will kill them. If your guy gets stressed out parasites can get on top of him real fast. Please do not "deworm on a regular basis" as it only leads to resistant parasites. Have your vet get a fecal analysis first and treat when necessary. It's only about $25.
There are a number of alpaca farms in your area that should be able to help out.
