im in the process of gaining trust with my grey aswell as learning not to fear his bites. what i started off doing was giving him a couple of monkey nuts (his favourite) then i went to giving him a peanut leading my fingers to go closer to his beak then half a peanut and now its quarter of a peanut i am now more calmer with him and he seems to accept it without trying to bite and his behaviour at times is when he goes for the peanut piece he stops sideways with his beak on my finger and stares at me for a few seconds then takes the peanut. so do you think he is testing me? also what do you think should come next from the progress? thanks
