You offered your hand sbd won't step up? Or a short perch?
When I hsve an untamed burd. I hold still when it fkyd. When it lands I talk sweet and walk over calm and offer my hand. Often they want to be saved from low places even if not tame. If they fly off I keep doing this till they get tired and let me rescue.
Or I must I pick them up with a hand on each shoulder holding wings to body. Then bring them close to my body but away from my face. I will get a bite or several I just steel myself and stay calm. Then put them back.
You n will need a much larger cage as soon as you can manage. I get ones used that look brand new wjth no rust. Clean them very well. From Facebook market place or Craigslist lidt or the likes fir a cheap large one. At least twice the width of your current Cage
