I built a Roost and finally caught a wild Partridge to put in it, but I'm only able to put Rye and Barley in the Roost slots, not the wild Partridge. I am able to put the wild Partridge in a Pet House. So what else needs to be done?
I agree that we need some kind of trading mechanism. As far as coinage, while is would be convenient, I think iron ore would make a good common barter commodity as it is widely needed for crafting and even a player just starting can mine it.
