Add to the list:
Can you make dung bricks for burning in the fireplace or outside if that sounds squeamish?
And how many per acre can you reasonably have?
Alpaca poo is fine fertilizer. They all tend to poop together. Some one gets the urge and goes to the the pile. Next thing you know they are all lined up to do their business all in the same spot. Makes it easy for us to clean.
They have tiny little “poo beans”, about the size of Lima beans than bear no resemblance to a cow patty or horse apple.
Lama/alpaca dung is like a rabbit’s, it would be a little hard to form a brick but I suppose you could feed them into a pellet stove like contraption.
It is very good fertilizer and they conveniently all pick a single spot and go there as a group and keep using it over time. Unlike cows and horses, they don’t poop where they eat. It is pretty easy to let it compost then scoop up with a front end bucket. Generally there was enough to fertilize a pretty good sized garden every year.
Oops, sorry...forgot to reply.
The basic rule is no more than ten per acre of pasture.
They will get almost all of their food grazing from May to Oct. but you need good grass to eat. We hay from Oct to May sine we have no decent grass over winter.
They eat about a half a bale per day total, maybe more deep in winter.
