What??  No!
Yes they are!
Collecting our poo?
Humans...
Do they eat it? Instead of grass?
Don't know but they're scraping off the ground and putting it in bags.They seem very excited about it.
I hope we don't  have to eat theirs...
Maybe they use to grow food?
Ah, right That would make sense.
Well, who knew? It takes all sorts.
Let's get back to grazing and make some more.

Alpaca poo is considered garden gold - you can put it straight on without needing to mature it or compost it first. Also it's very easy to collect  because alpacas poo in patches, not all over the place like sheep, and it's dry and odourless like small olives or large beans. See extra.
