Hi, I have a 6 month old girl who has been sitting in the nesting box all day (since 7 am). She may have left and gone back, I don't know... but I've been out there 4-5 times today and she's been in there each time. The other girls laid their eggs elsewhere, since I only have one box. The one time I approached her she got distressed, though that's normal for her when laying. But it's worrying me that she's been in there that long. What could be wrong and what should I do? Thanks.
