I had a slight ice ring starting around the upper rim on both the indoor and outdoor waterers first thing this morning, but that was it. The indoor one I have a thermometer in the lower part and it read 38.4 degrees. It was 2 degrees outside then, so I can't complain. Only had 1 frozen egg so far. Don't know when it was laid though as it wasn't in the nest box.
I'm a big meanie. I made a breakfast of whole scrambled eggs and oatmeal this morning and booted everyone but the chicks out around noon. Many of the younger birds were out yesterday and today. The "old biddies" hadn't been outside for at least 3.
