(I posted this in another thread but it got lost and buried, LOL) ***** OK stupid question: what do "drafts" mean in the chicken world?? I have a few small cracks in the wood of my insulated coop's south wall that cold wind could blow into and maybe push in through the contours of the really old windows (less likely though), is that considered a draft? I don't see where there would be any cross-winds since I patched up the north and east walls, the west wall faces the other old coop and has the main door... thank you ps: photo of the only uninsulated coop wall (west side). winters here go well below freezing, add the windchill and it's deadly. I need to keep my silkies safe! Oh and there is a big foam-insulated door that closes over the one you see there. I am thinking of putting a vent on that wall, near the ceiling as I have no ventilation set up?
