I'm in the middle of an order, and i'm not sure how much to get. There's 164 foot rolls and 87 foot rolls. (Something like that anyway.) I have about 30 chickens, 3 ducks, 1 goose, and about to have 2 goat kids. How much area do I need? I was thinking 164 might be enough, but i'm not sure. i have no concept of space.
