One thing I'd like to say is with the alpacas I've heard you can balance out the cost of their feed and care by collecting and selling their manure- it's kinda gross, but alpaca manure doesn't need to be aged like other manure and since they like to poop in the same areas it's a little easier to gather. It's also supposed to be really good for growing, but I've not tested it myself yet so I can't confirm that. Mix it with some potting soil and other nutrients and package it up cute you'd probably be able to sell it at a local farmer's market or to other farmers in the area fairly easily, especially with the price of fertilizer right now. For that reason alone I've considered having a small herd of alpacas, nothing crazy, and excess manure can easily be used for your own crops and garden. Waste not, want not, yada yada. I don't understand why they didn't try selling the manure, unless they think that's something dainty ladies like themselves shouldn't have to do. There's countless little old ladies with gardens and flowerbeds who're willing to pay extra to keep their plants healthy and fruitful.
