Can a disease stop a hen from laying forever

[ButchGood]

I have a flock of Astralorps and Buff Orps. All young hens laying heavily. One Astralorp got sick. Green runny poo, tired, laying down all the time and would barley eat. I isolated her immediately. She got through it and is a very healthy part of the flock. But I haven't seen her lay an egg since she got this disease. Its been at least 3 months. Can disease totally sterilize a hen making her unable to lay eggs?

Maybe the disease had something to do with her egg track?

Infectious bronchitis (IB) can cause a decrease or even stop egg production in hens that recover. Do you think she could be in molt? Being ill could have started a molt although most of my 18 month old chickens are molting now any way.
