I have a 7-8 year old female lutino Cockatiel. She's NEVER had a mate in all her life but she decides she's going to start laying eggs now.

She's layed 2 thus far, 3 days apart. The first egg I accidentally broke since I didn't even realize it was there. The second I have left with her since I know your suppose to leave them until they loose interest in them or she will replace them. She's not sitting on it (it's cold), but is 'protective' of it. I'm the only one that get anywhere near it or her but she loves me. LOL Honestly I think she thinks I'm her mate.

I had this happen previously with my first cockatiel and she eventually layed herself to death. She ended up with a prolapse (the egg was deformed and still attached) and died on the way to the vet. All my attempts to stop her laying were obviously not successful.
So now of course I'm worried that since she's started laying I'm not going to be able to stop her. I hope this is the first and last time she lays but in my experience this is just the beginning.
I know she'll more than likely finish laying this clutch regardless... but any suggestions to get her to stop laying anymore would be awesome.
Don't mind the cage.. I broke the bottom on the other one. This cage is temporary. And don't mind the messy cage I was about to clean her cage this morning when I found the egg and thought I'd post here first.
