it was 42 out, a fine mist was in the air, and we had north winds at 10mph. My birds were out free ranging. Yes, they looked like they were having a "bad hair day", but while I was bundling up to keep the moisture off, they were going about their day as if it was the most pleasant thing in the world (actually, they free ranged longer than they would have had the day been its typical warmth - it gets hot down here!
What a chicken considers "cold", and what we consider "cold" are radically different ranges.
/edit for reference, on the typical near 50 degree day, I would be out working in shorts, a t-shirt, and plastic shoes, wondering if I could ditch the T-shirt. Today I wore jeans, a sweater, and seriously considered socks and boots.
