I like that thought, but there's another issue.

Depending on their numbers, we don't have the means to TRANSPORT that much food.

We'd need to build several more carts, and teach the Ostrich Horses to pull them.

We could use the barge, but... it's slow, and it's Caelondian. And since I installed a turret on it, I don't think the Ura would be very happy to see it...
