Problem is the chickens (and their poop) are the top generators of moisture inside the coop, so during night is when they really need that ventilation, not during the day when they're not inside the space. Doors are not ventilation unless they're intended to be left open 24/7.I will have the window open during the day and the door to their coop going outside, they’ll only be in it in the evening/night
Agreed that those vents alone would be insufficient (though having a few of those wouldn't be bad) - you want at least 1 sq ft per chicken that can be left open rain or shine, night or day.I am going to pick up four of these to install on all four sides!
