How are you managing with 13 channels?

You have a chicken-farm. The chickens eat earthworms, but they can manage to eat the amount of earthworms a day on half the area you have. If you cut the size of the farm, you'll have more control over the chickens, and have to cut less grass (if you even do so).

Less apparent supplies may lead to a chicken, in this case a mapler to compete for the map needed if there is suddenly more chicken in the coop.
