I'm sorry you are going through this. Do you know how old she is and her background? If this is an ingrained habit even after all the positive changes have been made, it can take months to see the physical improvement in the feathers. Two months seems like a long time, but when it comes to habitual over preening and barbering, it really isn't.
What kind of diet did she have before you adopted her? What kind of diet does she have now?
It sounds like you are doing everything possible to help her. I know how frustrating it is, but guilt and added stress is non-productive. You should see an improvement as the damaged feathers molt out and new feathers replace them. Keep offering toys and activities to help divert her attention. Remember, you have improved her life in so many ways, she is benefitting from her new home and loving companionship. Hang in there and enjoy her company.
She's around eight, nine months old. Apparently, the owner of the pet store was friends with the breeder and for some reason, they gave her to them ever since she was a baby. So her background was just that pet store. And that pet store is notorious for mediocre care. I know she got some time out though; she bonded well with the associates. She had her own cage. It's just a stressful environment with plenty of whimpering and barking puppies, other birds, a cat across from you, a ferret next to you, and bunnies. So I can understand why she did that. She also only had one toy in her cage.
They gave her Zupreem color pellets and just a seed diet. There were peanuts in the seeds and different kinds, but she definitely wasn't on a pellet diet.
We changed it about maybe two, three weeks ago? She was not picky about the pellets at all. Of course seeds are still her favorite, but she eats the pellets without a problem.
She also has a cuttle bone for her beak, but she's intimidated by things standing up straight, so we had to lay it horizontally and also shave some in her food so she can have it while she eats as well.
We try to feed her fruits and veggies whenever we have the money (yeah, things are tight like everywhere else.) She loves to eat grape fruits, dried banana chips (but hates bananas), and apples. She's pretty picky about her fruits and veggies.
She has millot seeds at the bottom of her cage (we can't put it in something and hang it up. She's scared, like always lmao). So she's getting a pretty healthy diet all around.
When my partner is home, she's the playful one, so she loves to play with her. I'm the one she comes to for cuddles and just relaxing. My step son she goes to when she just wants away from us, lmao, and when she wants to get away with things because he's only 7; he doesn't know how to discipline without laughing, lmao. He's also a sweet, gentle kid and we do trust him with her. He's been exceptionally patient and he definitely won her love because of that.
Overall, she's just a loving little conure. They also said she was a Pineapple GCC, but I think she's more of a Cinnamon (someone else here mentioned that too), but the vet said because of her strictly seed diet and lack of veggies and fruits she was getting all of her life, her colors could be very, very dulled out.
Thank you. It's just worrisome. I do hope once her feathers come in she's alright. She's just such a little cute goofball and she really is happy, or else she'd be a nut job.
