I went to collect eggs early this afternoon when we got home and I had a Buff Orp around 25 to 30 weeks old who is laying growl at me as she was sitting in a nest box. So I collected eggs in the other 2 boxes next to her and came back to the house. I just went back there and she is still in the same box and growled again as soon as I started to walk near the box. What is going on? ETA: She has been in the nest box for at least 2 hours and was in it before I came home too.
