First time chicken owner here. It's been a warm sunny day in southern Michigan so I let my 3+ week old chicks outside for the first time today to explore their run. They were nervous but eventually the more timid ones came out no doubt inspired by the happy chirps of the braver ones who were feasting on bugs and lettuce. After watching them for a couple hours to make sure they were okay, I went inside. I came out this afternoon and walked up my hill to the coop and saw eight of them were lying on the front porch of their coop, on their sides, wings spread out, feet in the air, no sign of life. My heart skipped a beat and I ran toward the coop to find what animal have gotten passed my four lines of defense. As I got near the coop, the dead chickens jumped up and ran inside. Relieved but perplexed, I pulled out my copy of Keeping Poultry to discover they were simply sunbathing. What a relief! But I wonder, do chickens get sunburns?
