They're semi tame, they won't sit and let you pet them, but they don't attack either. Hissing is about as violent as they get.
I'm not sure what we'll do with them, they are pretty much just for pets right now, we may just sell the eggs for eating or hatching, I would like to try and hatch out some goslings for us though too. So, lot of possibility.

Originally, we thought we'd raise some for eating, but after getting them I don't think I could bring myself to consent to their killing.
