Last night, my EEers (from miss_jayne) finally figured out it was warmer up on the roost than it is right in front of the pop door. Other than that the chickens were perfectly normal. I have no heat or insulation and everyone seems great. The banties and younger chickens seem to be a little more wary of the cold, but the RIRs could care less about the weather. The ducks won't even go into their shelter at night. Goofy animals.
