Okay I am trying to figure out the balance of all of this. 8x8 coop, 4" vent all the way across the top front which is the highest point at 8 feet high. (single slope roof front to back). Window 2 1/2 feet above roost which is a cut out about 2' X8" with hardward cloth and wood shutter propped open about 6" out. I am leaving the door to the run open which is predator proof as you can get. 40"X40" window that slide open to one side on the east side across from their roost. Open all day as long as snow isnt blowing in, at night I put in a board and it leave about 8" at the top by 20" open. At night snow can blow in through any of those onto their backs. I have a temp and humidity monitor in the house to check it at anytime. When its snowing the humidity level in there has gone up to 86%. Frost on the inside of the window. I am putting vasoline on the combs at night. How in the world do you keep snow out, humidity level down when there is actually a storm? Or is it impossible. I keep reading keep it low, cut more vents, but that gives snow/rain more access. I am lost. Am I doing all right? Had a little bit of frostbite in November, but then started greasing up the combs on the very cold nights. It is due to be -22 here tomorrow and thats during the day! Right now 1pm in it is 9 degrees and 76% humidity in there and snowing outside. The side window is all the way open as wind and snow are not coming from that direction.
