Virtual Villagers--New Hut

I got Virtual Villagers yesterday and started playing. When I fired up the game this morning, my first hut was done, but my main builder was sick and the berry bush, my villager's main food source, was depleted. So I grabbed all my villagers (after healing my main builder) and got them all on research. The sooner I can get to the next level of farming, the sooner I can find a new food source for them.
