I have a hen that has always slept on the roost. She is 29 weeks old. Tonight when I closed the coop door she was missing! I found her in her nest box. She has never slept in there before. When I put my hand near her she screamed. Should I leave her there! Is she broody?....... She does like to lay on her eggs for the morning after she lays her egg. Then she gets up around noon or so, but she has never slept in her box.
