Even though your phone is gone the memories and smiles she brought to you are there for ever to recall often. You are extremely lucky in having some of her babies to continue her line. It sounds like she did have some sort of trouble with a tumour or growth perhaps the only way you can be certain is to have a necropsy done by the vet. Fly high and free little one
Thanks for your kind words....Indeed her memories are well preserved in my memory, the way she used to sit, chirp, sit on my hand whenever I inserted it in the cage and when she was quiet....she'd just keep on staring at me. I can't forget her....I hope she was comfortable in my home and that I was good to her.
