I went on a 3-day trip and had other people caring for my chickens. I came back yesterday evening and my 24-week old EE is not leaving the nesting box! She hasn't left the nesting box since this morning (10 hours) as far as I can tell! Last night, I had to take her out of the nesting box and place her on the roost after dark when I went to close up the coop, which is not typical for her. She has been laying me a blue/green egg every day or so since she started laying 2 weeks ago, but hasn't laid yesterday or today. Is something wrong with her? Thanks!
