Not laying in nesting boxes anymore.

[Blemay]

I have a dozen year old hens and they all just suddenly stopped laying in their nesting boxes. They free range my property all day and I have an egg hunt everyday. But they seem to all lay in the same place just a different place every day. Any advice?

You could put fake eggs in the nest boxes. Also...try not to let them free range until late morning.
