It is -10F with a windchill of -37F in Canada today. These Arctic conditions will linger another week according to the weather forecast. I have 2 inch Styrofoam insulation in the hen coop however the temperature inside the coop is not much warmer than outside. I will be going out directly to check on my flock they have been doing well so far (my 6 Golden Comet eggs production was down to 1 egg yesterday). That being said the girls are very vocal and active. My squabs (housed in 1/4 inch plywood barn no insulation) that hatched December 26 & 27 are coping well and I have eggs in another white homer nest. My ringneck 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.
