I've read some of the threads on here and although useful don't really answer my question so I am hoping someone out there can give me some advice.
My female ringneck is about 6 (or so we think) and is alone in the cage, she is a rescue so it took a while but with perseverance I became her 'person' which included lots of cuddles and attention. She went through her second round of laying in September, in the last 3 months her condition has deteriorated, I treated for mites, gave her a tonic and she started to improve. Then, about a month ago my loving little girl turned into an angry, bitey, impossible to approach bird and her condition deteriorated again.
She asks for love all the time but the minute I go near her she tries to bite, and has succeeded on a few occasions. I took her off to the vet, he dosed her up with vitamins, dewormed her and sent me home with palm oil and Nutricalm saying that I should start to consider rehoming her in an aviary.

Now, I will do for her what is best for her wellbeing and if this is it, although difficult I will do it but I was hoping someone had some input/advice/alternate suggestions?
Thanks
