Was -4 Celsius but is warmer now (it was 14C today!!) ill add my location, weather here is random during winter - was snowing literally a couple of days ago and today it was nice and sunny.
dimensions of the coop is:
Overall external (incl handles and nestbox): 124cm wide x 145cm long x 115cm...
its super rainy and temperatures are around -4. there is ice and snow on the floor, can I let my chickens out? I kept the coop door open and they went out themselves but then got so wet that I could wring them. and stayed frozen under a tree so we had to shut them in.
