I have a hen who has only been laying for about a month. Yesterday she sat in a nesting box all day, and all night last night. When I went out to check on her last night about 7:30, I did find an egg, about to fall out of box that I possibly could have missed earlier because I didn't check from the other side of box, so I don't know when she had it. She was fine, sleeping. She is still in box this morning, I gave her some food, and she ate it , but seems hostile toward me, makes "mean" clucking noises when I try to dislodge her from the box. Does this seem to be broody behavior? She doesn't seem to be in any kind of pain or distress.
