They do sleep together on a roost. I could smell a little ammonia yesterday but not that much. We cleaned the coop not that long ago. I added more shavings yesterday. The window we have is always open. We do have a door that we close. I could always leave that open too if you think more ventilation is needed. There is about a 3 inch opening all around the top edge of the coop (covered in hardware cloth). It’s hard to see in the picture because we painted the wire black. A humidity gauge is a good idea! They were all fine this morning when I let them out. I was hoping I didn’t find anymore dead ones.
The ventilation should be 20% of the area, or so I have read. The moisture/humidity in the appalachians is very high. And if it did drop I do not know what effect it would have on the air currents in your coop. If predators arent a concern, maybe wait and see if any more die and always have the option to open the door. The rain-cold combo is tough, at least a little further north in TN I remember some brutal winters camping. As long as there is no direct cross breeze hitting them.
