As to the fan, I would place (facing) the window, and have it remove the air from inside. The other open windows would bring in outdoor air. Inside of coop would be pretty much close to outdoor temps. Without fan ,,,, yes the inside could get significantly hotter.
I am not sure if chickens perspire thru their skin or not. I know that dogs do not. Wind would then not really cool the chickens then.
I know that drafts are bad for chickens during winter. What the draft does, is ruffle up the chickens feathers. Allowing warmed air to escape from the layer of fluffed feathers.
Lets see what others think about this.![Idunno :idunno :idunno](/styles/byc-smilies/idunno.gif)
