REFUGEVILLE

The real bugger is that I don't think we can just jump to chickens, as we don't really have any grains. I think, anyways.

Chickens can eat ground insects if I remember right, and like cats or dogs can supplement their diet with grass.
You really only feed them grain or vegg when you want to raise them for their meat. If we had multiple hens and a rooster that would be a good idea, but otherwise we have no reason to need that.
