Phantom egg laying??

[Slaneyrose]

I have a Barred rock hen that I got in spring of this year, along with a bluebell and leghorn cross. They all started laying several weeks later and all had different coloured eggs, so easy to tell whose laying. But about 3mths ago my Barred Rock stopped laying. A month later she laird one egg with no shell, and since then she hasn't played again .... BUT, I've started to notice her getting into the next box every morning and acting like she's laying, but there's never an egg!! What's going on? Can anyone tell me??

not sure what's wrong, but maybe give her some oyster shell to make sure she has enough calcium for her eggs.
