You definitely need to stop the cycle, if she is laying clutches close together. If this is once or twice a year, it’s generally OK. But when a bird does this every month or so, it gets dangerous for her health. With some birds, it helps to let her sit on the eggs. However, you should not provide a nest for her. The eggs can remain on the cage floor. You can’t stop her once she has started a clutch. She will lay up to 6 each time in general. Once this clutch is laid, if she doesn’t sit on them, then you can go ahead and make some changes to try to discourage her from doing this again.
There are a number of chances you can make to discourage egg laying, but you need to make all of these changes, not just one thing.
Limit her light to 8-10 hours by covering the cage early each evening
Do no give her anything to use as a nest – no bird huts or tents, no box, bowl, etc. If she decides to sit in a food bowl, remove it and replace with smaller cups.
Do not give her anything to shred such as paper or cardboard.
Rearrange the toys in the cage.
Move the cage to a different place in the room. Move the cage about once a week, or whenever she shows signs of nesting.
If she is let out of the cage, do not let her get in any dark cozy places.
When you handle her, limit any petting to her head and neck – do not pet her on the body.
If there is no metal floor grate, then do not use any bedding or paper in the cage tray – leave it bare and clean it daily.
If she continues to lay eggs anyway, then you may have to take her to an Avian Vet for a hormone implant or shot. The implant seems to be more effective and lasts longer.
