My chickens have recently started staying out late (after dark). they stay near the house and coop and are pecking and scratching in the dark. They will even run through the leaf litter at me in the dark which catches me of guard sometimes. Is this normal? With cooler temps I would have figured they would turn in early if anything. Eventually they all find there way into the coop and we don't have to gather them up or anything. My biggest concern is the greater exposure to predators after dark. They have also been honking like geese in the morning the last couple of days before we open up the coop.
