I contacted a woman that has over 30 years experience with rescuing and rehabilitating Australian wildlife this morning to discuss my issues with Opal. After spending a couple of hours talking over the situation with her she recommended that we rehome her ASAP as she is suffering from increasing levels of stress. This is why I am unable to progress with taming her. The combination of my dogs, living on a busy main road and being able to hear the other birds are making it impossible for her to adapt to my home. It is too noisy and too busy for her to relax. We have discussed it as a family and have decided to follow her advice. It would be selfish to keep her in an environment that she finds distressing, ignoring expert advice, to keep trying to tame her.
