How many heaters should I put in my barns and coops?
One heater per building is enough. Putting more than one doesn't really change anything
Heaters matter now, I'm not sure if its from an update or not, but with one heater 2 chicks, 2 ducks and 3 rabbits one heater gave me ZERO goods production and hearts were dropping, money is no object in the game any more so I added a bunch I think 4 per building and things are back to normal.
