I think my young (under a year old) barred rock hen is trying to go broody. I was gone last night & got home late tonight. I did collect eggs yesterday before I left but tonight when I got home & went out to collect eggs, she was sitting on eggs in the nest box & put up quite a fuss when I went to get them! I'll see in a few days if she is serious or not. If she is I'll sequester her as the last broody in that coop wasn't successful because everyone kept periodically adding eggs to her nest.
