This morning around 5:00 -- still completely dark-- my husband saw the girls up and about out in the run. (Yes, the run is fully enclosed and as critter-proof as we can get it...) Our coop/run is not lit. The sun doesn't come up lately until around 7:00. I thought they were night blind. How and why would they be up so long before sunrise? Our neighbor's famous barking dog does tend to have a barking spell around 5:00, but we didn't hear one today. There is a street lamp one lot away, so it's not completely dark. Would that be the reason? Or should I suspect that something got in there and woke them? There was no evidence of any critter getting in. Anyone else have chickens up and at it in the dark?
