One of my hens did the same. Something to do with shell formation? Be interested to see what the group says.

pretty firm inside but no sign of yolk or white just rubbery all the way through she had finished laying or so we thought

 

[napoleon]

No shell just this rubberyness all the way through she had not layed for several months
