It is -10F with a windchill of -37F in Canada today. These Arctic conditions will linger another week according to the weather forecast. My squabs that hatched December 26 & 27 are coping well and I have eggs in another white homer nest. This loft is not insulated and there is only 1\4 inch plywood between them and the elements. My ring neck pheasants are enjoying my extra trips to the buildings and wondering what all my fuss is about. I shut up my ventilation ports yesterday because of the cutting wind but may open a few today if there seems to be vapour in the buildings. I open my double doors first thing in the morning that changes the air inside the building in about 5 seconds.
