Well said. Thank you.I hope everything works out and you are able to keep your Goffins, but I just wanted to add my two pennies' worth here. There is a stigma in our society - I see it bad in the dog rescues I help with, I see it in many parrot owners and rescuers, etc. - that people who relinquish animals didn't try hard enough or are bad people. With parrots especially, we are bringing challenging, emotionally taxing and potentially physically dangerous wild animals into our homes hoping they can adapt to a captive situation. Most of us who do research and overprepare find we get a new companion we can at least live with if not adore. But it doesn't always work out. Some people and parrots just aren't good matches, and while I think people should always put in the effort to change the relationship, sometimes the dynamic just doesn't and can't work out.
In dog rescue, I know people who struggled with serious property damage from dogs with severe separation anxiety and even one couple whose new dog ended up hanging themselves from a car window...all because they were afraid of the stigma of admitting the dog's problems were too much for them. I know people whose new dog ended up killing their original dog. They saw the aggression, but were scared to admit it wasn't working out and be blamed for it. Sure, there are simple fixes and in many cases the people just didn't have the experiences and resources for those animals, but they were afraid to admit failure. Here in my town, relinquishing an animal means you will never be allowed to adopt again from most of our shelters.
Anyway, it's a long tangent but if the animal truly isn't working or has become dangerous to itself or the household, there shouldn't be a stigma attached to relinquishing or rehoming that animal. Cockatoos take an extremely dedicated owner and even then, some toos just won't work in some situations. I hope you try whatever you can to keep your bird at home, but ultimately if it doesn't work out, please don't feel that rehoming is a betrayal or makes you a failure. In any case, good luck.
