Boy, do I ever have an egglayer. Maxi pionus scared me half to death with her binge that lasted about 9 months. Her eggs became so soft they broke during the laying and stuck to her belly.
My vet had me move Maxi to a quiet room and slowly reduce her daytime hours--all the way down to only 5 and a half hours of daylight per day. I had to cool the room down, too. Sounds cruel and I felt like the meanie of all time but she was getting in trouble with all those eggs. Every day I walked in her room expecting to find her dead in the floor. It was awful.
Do be sure her calcium intake is good. I finally started using a high quality calcium powder because Maxi went on a strike against good foods.
And please don't use my method without your own vet approving it because you need support during this.
Maxi skipped this year with the eggs, thank goodness. Got a bit chirpy for a few days so I caged her every time she acted hormonal. She invites my African grey to mate and he obliges if I don't watch them very carefully. She is used to complete freedom in my birdroom for 12 hours a day. The caging seemed to settle her back down--at least for now. I will put her back in isolation if the caging doesn't continue to work. I don't think she would live thru another 18 eggs in one season.
I avoided drugs for her but will resort to them if we have another episode like that last one.
I hope you will call your own avian vet for advice. S/he may know of another method to settle your bird down.
