I got a new budgie 5 days ago and I’m new to owning birds. I’ve been keeping him on my desk, constantly showing him my hands and talking to him and talking to him while I clean/ refill his cage needs... I have two problems. He won’t take treats out of my hand or even stand on it, and he has a little food tray with a step he constantly bites for about an hour at a time for a few hours a day even though it’s full of fresh food every day. How can I get him to be less stressed out and tame with me and why is he biting his food tray so much?
