Here's what I do for the heat in the coop.................
Along with the great ventilation of 2 windows, (one of which you can see in the picture below, behind this small fan), a 'ridge-vent', and two 8 x 14 inch, louvered vents,
up high on both gable ends.....(one of which you can see in the picture below, above the fan).....I also have my summer help of a
small 10 inch 'box fan' on a shelf.........about 3/4 of the way up from the floor of the coop to the ceiling..........
And a 16 inch, wall-mounted, oscillating fan on the opposite wall......blowing 'toward' , but 'above' the level of,
the roosts..............
I am lucky enough to have electricity both 'in' my coop and 2 feet away from the outside of the run, on a side-wall
of my barn. I do set up a 20" box fan.......bungeed in place......blowing 'into' a corner of the run.......for those really hot
summer days. The girls seem to really enjoy this breeze, and 'do' sit and lay down in front of it.
The fans 'in' the coop are essentially for those hot, humid nights......when the chickies are in there sleeping!
The fans create a nice breeze when there isn't one!
