HI I am new at this and have been reading alot. Maybe I am being dense or something, but I cannot understand how my coop can be well ventilated while not being "drafty". Literature says that it needs to be ventilated...........I live in a northern climate (Adk. Mountains, near Lake Placid, Ny and the Canadian border) so it gets cold here. I understand that a draft (wind blowing directly on the chicken) is not good as the chix will lose heat...........so how can I do both? My coop has an area at the top of the ceiling over the door, under the eaves that is screen. Will this be okay as it isn't directly near where the girls roost and the wind won;t be blowing on them ?........... Sorry, I am having trouble envisioning how to do this the right way. Many thanks!
