My year-old BO is in a serious molt, poor sweet thing. When I tucked them in tonight, I noticed she is sleeping in the nest box instead of on the roost near the window as usual. Is she cold? We had a VERY warm day here - in the high 70's at least. It's probably in the low 50's at night. We don't have heat in the coop - they were fine through the last winter. My other hen, an EE, hasn't shed a feather yet. Is each bird on its own schedule?
