Just got 7 new Norwegian Jaerhons. they are my first chicken s. I got them setup in a small 1 meter X2 meter coop. 250 watt heat lamp above and a seedling heatmat under the box they came in which is on its side. The temp reads 107 between the heatmat and the box. The box is kinda thick and there's a bit of bedding down that came with. I have rice hulls down in the floor of the coop, 2 little food dishes and a gallon waterer. The inside temp is about 80. I am hoping they make it, unfortunately rainy season is here and ****** off at the humans. if the chicks have a rough night I will make them a spot inside.
