I'm worried about this too. We aren't even in the height of summer yet. I have solar powered fans on order that I plan to add to the vents to pull the hot air out. At 10 pm it's still 80 degrees out. My coop is in an enclosed run, so short term I am leaving the access door off of the nesting box for extra air flow.Right there with you. I was under the impression for some reason that they would actually open and close and adjust up and down, almost like blinds. But no. For the investment, I'm pretty disappointed and frustrated. I expected much improvement over the cube but it's just not there.
It was 84 at 11:00 PM last night. I'm already disgusted with this heat. We are ten degrees above normal, whatever that is anymore.
I like the idea of moving to Montana and living in the mountains, but my husband isn't having it. DANG!
Our girls are struggling bad today, we have two fans running on high, one on the back end under the coop and one on the front end up high in the run. Cold water replacement happens frequently in this heat and I'm afraid they will get watermelon toxicity - is that even possible? They get two helpings of watermelon daily in this heat. It really helps to cool them down. And what's happened to the price of watermelon?!!
We can't even spray water on the run from the hose as it never cools down. Imagine turning on your faucet in your kitchen in the cold position and the water is warm.
Sorry for the rant. We'll all get through this somehow.
