I have an older production hen that was still sitting in the nesting box when I just went to close up. I knew she wasn't broody as she's never gone broody and wasn't puffed up or screeching. Thought maybe she was just getting old and was more comfortable there. I picked her up just to check her and when I did she released what looked like egg white. I'm not sure if she's laid today or not, she wasn't on an egg in the nesting box. What should I look for or possibly do to help? Like I said, she's older, about 5-6 and a production bird but even if her laying days are coming to an end, or her days in general,I don't want her to suffer.
