I wanted some help in ventilating the coop better. One of my chickens got frostbite; I believe it is because I don't have enough ventilation in the coop.
The coop is not yet completed as it still needs work, but here it is hopefully you guys can help me

(Note we added holes in the top, but it was clearly not enough).
This is the top lid of the nesting boxes (metal thing is the handle).
I have opened the lid of the nesting boxes a bit to get some air flow.
There is this little window, but it is just covered up.
Please let me know what I can do

Thanks
