Our chickens are 9 week old and have been free ranging for a week now and loving it. So far, I have had to gather them up and put them in their coop every night but the second night. I keep hearing people's chickens put themselves to bed just at dusk....mine are still out roaming at 8:45pm and I have to either lure the willing ones in with mealworms, and actually catch and carry the other stragglers. I'm afraid to wait until it is dark to see how long they will stay out....I don't want it so dark that I can't see them. Will they figure this out eventually??
