I knew little Puff would likely freeze to death if she wasn't in a sheltered place So we went out with flashlights and looked everywhere. Betty then found the courage to dart across the yard to the coop, but tiny baby Puff was nowhere to be found in the dark. She's very tiny and black so is hard to find when she hides. When we got close to her hiding place under the deck, she came out and I picked her up and carried her to the nice warm coop (about 45). She was very happy to be rescued. Bert followed me, he had stayed with the baby to keep her warm or else she would have certainly frozen (Bert has done that on 3 occasions with other hens, risked his life to save the hens).
Today, it was below zero all day but it was about 60-65 in the solar heated Aviary. The Chickens were basking in the sun like tourists on a beach.
The Pigeons stay in the aviary at night (Ambient temp) so I have covered nests for them with a small elec heater. Sometimes they sit in the heated nests but at night they prefer to sit in the aviary on perches, even at 20 below zero (like tonight, the WindChill will be -30). I put them into the heated nests (about 20 degrees) but they come right out again. ? oh well, they don't seem to mind the cold.
Maybe they need electric blankets?
