This morning our daughter got up before we did and came into our bedroom and said, "Why are Whitey's feet hurt?" (yes, our daughter who was 3 at the time names our chickens based on color) My heart sunk then raced... The only reason she should be able to see a chicken is if the coop was left open the night before... and when the coop is open there is usually a VERY high probability of massive coon caused carnage. In a dazed stupor I threw on some clothes and went outside. I was expecting bodies all over but was so relieved to find the coop shut up tight. We don't know what happened, but somehow Whitey got left out. Maybe my auto coop door closer went off too early, but more likely she flew over our fence and couldn't get back in. We've lost a good number of chickens (and duck) from leaving the door open too late at night or not closing it. It is the worst feeling to wake up thinking that all your flock may be dead because of a simple mistake.
