Broken egg inside

The last week & a half have been a nightmare, what with the red mite, breaking a finger & now, my oldest hen, Rosie, has had a soft shelled egg break inside her.
I have bathed in warm water & washed her rear end, & pulled out the shell, which was hanging out.  She laid yesterday & the egg was normal, but covered in the white, so I knew something was up.  Will this harm her in any way? Hopefully I have made her more comfortable now, as she had been in the nest box all morning, obviously trying to get rid.
Any advice greatly received. 

Thanks Foxy
