Yes, it is pretty common for older hens to have egg laying issues. 8 qualifies as an older hen.I have a 8+ barred Rick hen. ... She has been with me a year and never produced eggs. ...
so- is this normal for an older bird.
I'm not sure why she is trying to lay after a year, maybe the days getting longer. I have no idea how long that will last if she went a year without laying.
I'll leave suggestions up to others as I have no experience with a hen that age doing that. She's obviously a pet. I wish you and her good luck!
