Egg Laying Age for Lorikeet

I have a female "Rainbow Lorikeet". She is 12 years old, in human years.
She has never been bred.
For the last 10 years or so she has been laying eggs around every 3-4 months. The last time she laid eggs was about 5 months ago.
She seems healthy enough, but I wonder if I should be concerned.
Do you know if she should continue laying eggs, or is she too old, or maybe she will but not as often?
