Pertaining to the coop below, is leaving the door open and having the top vent open enough ventilation on these muggy humid nights? i live in VA which will get fairly hot and don't want my chickens to get overheated at night. I could always remove the window for extra air flow if need be. another option is cracking the back door (the entire back swings open). do chickens prefer to roost within 4 closed walls? i figure they would readily roost in a tree if no coop was available so they probably wouldn't be bothered. the only issue would be if it rained. The kennel is as predator proof as its going to get so i'm not too concerned about access to the coop through the night. create more vents under the overhang/remove window/prop open back of the coop? I currently have 3 bantams (2 hens and a rooster) and 3 buff orpingtons (4ish months old) in there, so its pretty full, maybe too many birds once the orps are full grown. I'm considering expanding this coop or building an additional little one for the bantams when 2 blue orpingtons arrive in a few weeks. i just don't want my crew to be hot and uncomfortable!
