Hi, another newbie, been watching you all for a while and thought ok will go for it, so here i am.Here i am with a grey sweet as pie one minute and trying to chew my fingers off another minute later would be grateful for any advice, previous owners told me he was a sweetie who steps up on command and is very friendly not with me and mine he aint, could i be doing something wrong?have had parrot before but not a grey.
