We keep 8 Buff Orphingtons in a mobile coop on our suburban property. We wanted to ensure they would be warm enough to continue laying over the winter so we constructed a "coop hoop" greenhouse. With a DROP2 Temperature and Humidity logger we are able to confirm that our chickens keep themselves remarkably warm even on sub-freezing days. We also receive alerts on our phones when we need to vent the hoop house to ensure they don't overheat.
