I know that sometimes there can be another impacted egg.
I've also read that this can just mean she is comfortable in her environment.
What should I look for now?
A crossover Quaker Scuti (F), A Sun conure named AC, A Cinnamon Green Cheek conure Kent, and 5 budgies, yellow (m), clark Jr. (m), Dot (f), Zebra(f), Machine (m).
What you should look for now is an avian vet appointment, if just for a checkup.
Your Parrot list just includes one amazon so I assume the egg is unfertilized. I'd get the appointment in first, but if all goes well he/she (the vet) will probably say sneak the egg away so she doesn't fixate on it.
For now I'd say make a generic checkup appointment and bring it up.
don't worry too much. Up the calcium in her diet for a bit, scraping cuttlebone over food or baking an egg shell and crushing it up is good so as to avoid egg-binding. Check her abdomen to see if more are coming, you can normally feel it, sometimes even see it. If she takes more than a day with an egg in her but not laying get to the vet, if she passes the egg then let her sit on them and do her thing. There's no risk of babies so after a week or so she should get bored and leave them. Only when she shows no interest remove them otherwise she may keep laying. I've never heard of a bird becoming fixated with their eggs outside of natural nesting instincts.
Try moving the cage around too to help kick her out of hormones and of course limit daylight ETC
It is reasonable to expect another egg to be laid in the near future as they generally come in two's.
"The number of eggs in a clutch varies with subspecies. Yellow vented (Vosmaeri) generally lay two eggs per clutch. Blue bellied Eclectus (red sided) can lay three eggs per clutch, and Solomons have been known to lay as many as four per clutch."
Certainly put a call in to your CAV for professional guidance and see the second attachment for useful info on how to manage and try to decrease laying. I am unsure if you should wait to implement these measures until after a second egg has been laid or if it is safe to do so now? Thus advising professional guidance.
I havent experienced egg laying (Wrangler is a male) but from all I've read from other female ekkie owners, more often than not removing the egg before she is bored with it will prompt her to lay a replacement. You may have to run the entire 28 day cycle.if you're concerned about the egg breaking just replace it with a fake egg.
