Do all coops struggle with heat in the summer?

Here is a picture or our original coop. We have since built a much bigger one but my original 3 girls still want to sleep in this one...keep there door open and made this temporary framed hardware cloth insert for the warmer days. I assume you have a big door to clean your coop so this could be an option for you. Last year we would also put a fan on them through this door and then eventually I bought a swamp cooler and put it in front of the door at night to keep them cool. I can be a bit extra with me chickens!
