So my chickens are six weeks old. They've been in the coop with a heat lamp at night and going out during the day. Last night was their first night in the coop without the heat lamp. Temps were in the mid-70s during the day, but it was windy and it dropped down into the low 40s over night. Today's windy again, but temps are in the 50s and it's partly sunny, and they've stayed in the coop all day. Moreover, they've been on the high roost most of the day where, presumably, it's warmer. This is the first time they've been roosting during the day. Most of the time they're in the coop, they're scratching around in the shavings. I have two theories: either they're cold or they're spooked by the wind. What do people think?
