Helo my girl has a lump on her head.i brang her to a Evian vet and tried to put a few medicines. She still is bleeding actively.

Hello everyone, my dad has a blue & gold macaw, he’s had her since she was 8 months old, she’s now 32, shes always been a healthy & happy bird, loves coming out of her cage, shredding junk mail, rubbing her beak on the carpet, etc

The issue is she started laying unfertilized eggs for a while, at least once a month. When she was 20, We’d wait for her to get “bored” of her eggs and take care of them. She later eggs for about 5 years but when she stopped she started plucking her feathers nonstop. She’s bare on her chest, her legs, her back.
About a year ago she also started having night terrors and has been difficult to get her out of the cage. She also tries to bite more now. We’re not sure what’s causing all of this or if it is all connected somehow,
We’ve taken her to numerous vets and have done various amounts of testing which come to show no medical relation, her diet has consisted of seeds, pellets and some “people” food, one vet also tried to prescribed her an antidepressant but that seemed to have no effect/change

We’re at a loss cause, my dad is thinking it’s best to put her to sleep but we’re trying to avoid that unless absolutely needed to be done.

First pic her before she was plucking, 2nd is what she looks like now ish (shes more bare on her chest)

Please help, thank you in advance!

Edit: my father does NOT want to euthanize her, we’ve called many rescues for advice and possibilities giving her up but we’ve gotten told they’re full, & has gotten stoned walled
He fears it is the only option left and we’re trying all of our resources

My parents had issues with pregnancy and chose to give up on kids and got her, then they did IVF and got pregnant with me, I’ve grown up with her, she’s my childhood pet, my dad is 63, I’m 26, I’m supposed to inherit her because well she’ll outlive my dad. We truly do not want to give up on her, we love her dearly and just want the best for her. We certainly do NOT want to euthanize her. She really means dear to us we’re just running out options to help, thus why I’m here 😕
