I am in Houston.We are on a cattle farm outside Houston. Thank you for all your help. We are making some changes tomorrow. You can't tell but the entire coop is reinforced with hardware cloth. I think you are right and is too dark and scary for them.
They aren't going in there because it is TOO HOT.
I have an open air coop...my coop is almost all hardware cloth/open because it is too hot down here.
It will NEVER get too cold down here for our birds, I promise.
