I know this my sound funny but I think my chickens eat during the night. I check everything at dark and I am in the coop at daylight an the food is almost gone? They are 8weeks old. I hatched 15 an that is all that is in the coop.(new coop no mice or rats) At dark their on roost and when I go in in the morning they are still on roost? Any one else have this going on?
