I apologize if this is in the wrong place or too long or has been answered before but I've never posted in or belonged to any forum site before and need help! So my girlfriend had owned a greencheek/yellow sided conure for about 5 years from a baby when I started handling it about 2 years ago and it has since decided I'm the only one that can touch it without being attacked including her so it has more or less become my bird which is fine except we just moved to a new apartment and this is his first experience moving and since we got here about a week ago he no longer let's even me touch him. He's fine taking treats from my hand and will happily come out on his own to hang out on his top of cage play area but if I hold out my finger and say step up he bites. Not an out for blood I'm going to tear your finger off bite but hard enough to show he doesn't want to be touched which he's never done before with me before but the same day we moved him I also went along with my girlfriend to get his wings clipped which I've never attended before so I don't know if it's him being scared of a new environment or not trusting me any more or both and know basically nothing about birds since I just kind of ended up with one and never intended to have one. Hes also suddenly started grabbing a single tail feather with his beak and bending it forward to stand and hold in one foot and im wondering what that means, i couldnt find anything online about it and I would really appreciate some input on possible causes and solutions because I obviously want him to be happy and not feel threatened in the new house and am used to being able to take him out and walk all around with him and hang out all day with him on my shoulder and miss my little buddy. Also because I know next to nothing on birds, any advise whether it's relevant to this specific problem is more than welcome too!
