I had a broody hen sit for an extra week w/o a problem. (It took about that long to obtain some fertile eggs.) I'm not sure what the upper limit is & that sounds like a very, very long time to ask a hen to set. (My opinion, not fact.) Try asking the people on this thread:

They are very good & also quick to answer questions. Good luck.
Thank you.
