Sometimes I will let the chicken free range during the day and they will go in at night. in the last month a few times I got home later and wasn't able to make sure were all inside coop but locked it up only to find 1 to 3 chickens still out side. They must have been hiding under the deck where they like to go. Is there away to stop this? Is there a reason why they might not go in at night with the rest of the chickens? Also the chicken should start laying soon should I stop free range until they start laying eggs and using the roost box? I'm worried they will lay eggs under the deck where we cannot get to them. The desk os to big to block off.
