It was 21 below zero this morning here in the southern Rockies. It's since "warmed" up to 5 degrees at noon. I had kept all thirteen hens and two roos inside their respective coops all morning because I was afraid of sending them out to get flash-freeze dried. I just opened the coops, but only the youngest hens came out, and now they're all huddled together, fluffed up, on their favorite perch in the pen, which is enclosed in plastic sheeting and roofed. Only one roo, the one that can't get enough girl watching, came out, but he spends all his time standing on first one foot and then the other.
How cold is too cold to let them out?
