Chris MD, I appreciate your reply and it helps me that you own an ekkie. But maybe this is a special case. For starters, I am being given this advice from a woman who manages a lot of adopted parrots of all kinds. She is not a novice when it comes to adopting problem birds including 2 other ekkies, several maccaws, CAG, and a cockatoo.
The other factor is this specific female ekkie's history. Her original owner (male) of more then 15 years sexually overstimulated this female through way too much complete body petting, private hutch, and etc. Then he passed. The wife then try to care for the bird, got bit, and then basically ignored it other than feeding. The bird's body is completely bald from five years of solitary confinement.
The current owner, who deals with many adopted birds, has repeatedly tried to have her mate with numerous male ekkies. She has shown no interest whatsoever. She only responds to human males like her initial owner.
Maybe after having hormones triggered on for almost her entire life that such a hutch has become a biological necessity? Just throwing out thoughts. I can't ignore the current owner's guidance as she clearly has worked with lots of parrots of all types. I posted the question here in hopes that someone might have some similar situation.
