Is she or isn't she?

The guinea hen was sitting on her eggs!  But was she setting?  Or just laying an egg?If it´s the former, there might be a couple chicks in there, because of the hen who lays in there (cuckoo, cuckoo!)The two boys were on the roof, raising hell.  Screaming in a way that drew me to check if anything was wrong.  Crazy raise-the-roof-alarm yelling.She´s sitting on eggs! She´s sitting on eggs! She´s sitting on eggs! Sitting on eggs! On eggs!  On eggs!  ON EGGS! EGGS! EGGS!Really, all the yelling about it seems maladaptive.There she is in there, sitting on some eggs.(She wasn´t setting, just laying one, probably).Good, I need time to put a chick fence on the door.  I didn´t think that through - a coop five feet off the ground - what if she hatches her chicks in there?  They´ll fall out.  I´ll have to block them in for a few days until they can do a controlled landing/flutter.
