SF Chicken Coop error

my chicken coop is "dying".  when i try to give it grain it responds with:

[15:11] SF Chicken Coop: Error! Required tower not found within range

[15:11] SF Chicken Coop: AutoFood: Off

it is right next to the tower.  what it needed to fix this?

You should look in the config notecard in the chicken coop and check the following:

FOODTOWER=SF Storage Rack

WATERTOWER=SF Water Tower

The names need to exactly match the name including if upper case or not etc.  Also, both need to be in the same group as the coop.
