Your idea would work if the window and fan were large enough that the air inside the coop migrated out to the warmer air faster than the warm outside air would replace it. It becomes a problem with efficiency. How large would the window, fan, and ice packs need to be in order to accomplish this? I believe the window would need to be larger than the coop. And/or a very weather sealed coop restricting the amount of air-in ventilation.
A swamp cooler doing the same thing but in reverse, would be much more efficient.
What is a swamp cooler? If you go by the refrigeration law that warmer air always migrates to cooler air, then it is impossible for cooler air inside the coop to migrate to warmer air outside the coop. I think the only problem would be when both the outside and inside temps are the same (because of warmer air moving to the cooler air thus warming the cooler air), at which point -- instantaneously -- there would be a battle of which air is warmer. I think the issue of efficiency is going to have to do with how long the icepacks can withstand the onslaught of ambient air warming them up.
