I see and agree that you need to do what is best for Sydney. I think it depends on what kind of re-hab he needs. If it is just trust and bonding and he is capable of that, it might be better to move him sooner. If he is deeply hurt and disturbed as a result of living in those poor conditions, he may need more time or a lifetime. Does he seem really resilient or barely resilient? I also think your son needs to weigh in on it--as you point out, bonding goes 2 ways (three it seems: for you, your son, and Sydney). I also think his vet visit may impact the decision. If so much damage has been done that he doesn't have much time, then moving him from the safety he has just re-gained would be sad. If there is nothing chronic and serious... that is a different thing. I don't envy your position of deciding between re-hab and re-home. I have been around a variety of birds and each were so cool in their own way. When I my friend got a Grey, at first I didn't understand. Of all the vibrant choices, a Grey seemed plain. But they are beautiful, expressive, intelligent...I was so lucky to meet Grady when he was so small and watch him grow. And when I met his sister, there was no way I was going to let that beautiful, sweet bird go to a breeding facility. I think I also saw you have a Grey, I've always heard that Greys only flock with other Greys, Louise knows who Grady is and calls for him--and I don't mean squaws and whistles, she yell his name. If Sydney stays with you, he will have a buddy.
