Should I get an exhaust fan?

[AshleeW]

I live in Bellevue Nebraska, I have seen coops with exhaust fans and without. I am not sure what I should do? Should I get one? Why don’t some have it, are there other options to move air through the coop?

Exhaust fans are nice to have but require electricity and regular cleaning and maintenance. The other option is to have large vents placed in such a way that they provide ample cross ventilation but won't allow drafts to hit the birds, such as in the eaves. Rule of thumb is 1 square foot of vents per bird that stay open 24/7/365.
