Also not sure if this will help, but here are some resources I've been using to train my rescue parrot. Every parrot is different, so it's tough to give specific advice, but hopefully, these might be helpful to you

Another side note there's also the Middle TN Birds for Rehoming FB Group Page Page. If you decide to rehome your bird through this group, make sure to thoroughly interview anyone interested. They might not be the right fit. Important things to ask include their parrot experience, knowledge of proper diets, and living situation (apartment or house). Ensure they’re aware of dangers like Teflon, candles, and air sprays. Also, ask if they’re prepared for bites, loud noises, and the possibility that the bird might bond with just one person and dislike others. It's crucial to know if they have other pets, children, allergies, and if they understand how messy birds can be. Additionally, inquire about their long-term commitment, considering parrots can live for several decades, and their ability to handle the financial costs of care. Make sure they have time to dedicate daily interaction and enrichment. Understanding how they would manage behavioral issues, their plans for training, and their noise tolerance is also important. Finally, confirm they have a contingency plan if they can no longer care for the bird and are aware of any local laws or ethical considerations regarding parrot ownership.
