I don't understand people sometimes!!
I'm not sure how this bird wound up well adjusted but can almost promise it was in spite of being Alpha rolled!!! Poor bird must have been terrified
I know I'll get some negative comments from this but it has worked for me. Years ago, I spoke to a bird trainer and she said that birds have a pecking order (no pun intended) like dogs and humans and dominance needed to be established. She told me that when he (my grey) bit me to put him in a submissive posture (on his back) and calmly tell him "no biting" a few times then release him. Obviously, since he was riled in the first place and to save myself from being bitten again, I would have to get a towel or something to protect my hand (much like you see them do at a bird grooming). When this is done, I would remain very calm, even though blood was spurting from wherever it was, and let him know I was in control. This isn't for everybody, and my husband is too afraid to do it but my bird and I have a very close relationship. He has gone from a bad bite every 3 or 4 months to maybe one a year. I think it's actually been more than a year now. It is true, they are very smart and cognizant of fear and will take any opportunity to nail someone they don't respect. My guess is that your husband needs to build up the respect between them. My bird is very well adjusted, exercises three to four times a day, and a non-plucker.
