Hi Sanzoni, so sorry that things are not going well with your baby grey. Something has caused your grey to be leery of you and your family. Can you tell us what your routine is with your grey? How you and your family interact with him? Perhaps with some deeper information, some help can be provided. Have you talked to your grey's breeder about the problems you are having as he/she would know your grey best. If your grey had an unpleasant experience at the vet, this can take time to get over. They are very intelligent. Being calm and understand is an important plus. What is your grey's favorite treat? That is what I would use to get him back in his cage. I also use my arm has a step up perch for my grey. It is much more sturdy than a hand/finger. Grey's do use their beaks to test if a perch is strong enough to hold them so if you pull your hand/arm away when your grey reaches out to test it with his beak, you might get bitten if your grey is trying to steady his perch. Patience is the key to earn our greys' trust.
