Ok, so one of my Americanas has a new behavior that has stumped me. The coop light goes off at 4:30pm which is promply followed by all my girls assuming their spot on the roost. I usually go and close the coop door shortly after dark and check for any late eggs. The last four nights or so I have had the same Americana sitting in the same nest box after dark. She is not on any eggs and is sitting with her tail feathers up and her body feathers fluffed. Same as the others look when laying. Why is she doing this after dark all of a sudden, and can she get to the roost in the dark?
