Age a lovebird can no longer breed? Anyone with older pairs?

[Gigi’s Mom]

I have raised lovebirds for many years and have had varying ages when the hens will stop laying or lay non fertile eggs. I am curious if there is an average age where lovies become too old to breed? Does anyone have personal experience with the breeding ages of their lovebirds?

Sorry I don´t know the answer. I even checked the Lovebirds Compendium and there´s nothing about being too old.

I think it is the bird that shows when they´re done, by deteriorating health, unsuccessful clutches/more problems in the nest where there weren´t previously, fewer eggs, etc
