I have a flock of 19 hens (no roosters) and one of them has gone broody on me. This has been going on for over a month now. She does come out to eat and drink (and push the others around some), but spends most of her time in the nest box. I can reach in and get any eggs she happens to be on so she is not overly aggressive. How long should I expect her to stay broody or what can/should I do to break her? If she is still like this in the spring I may just go ahead and get some fertilized eggs and let her do her thing.
