I'm concerned about Nigella, our austrolorps. She was fine at dinner time last night. When I went out later to lock up, she was up in her box, all flattened out. This seems to be her characteristic posture when she's laying an egg (she's in there for a couple of hours sometimes). So this was right at dark, so I assume she would have gone to sleep shortly thereafter. I go out this morning, and she's STILL in the box. First I thought she was dead, but I touched her back and she made her little sound and lifted her butt a bit (note: she has NEVER let me touch her during daylight before). So I'm wondering, did she nod off during last night's egglaying and she's just taken up where she left off? or should I be concerned? Any thoughts?
