stubborn

Every time I try to get him to step-up, he either flies or runs away. Which is weird because when he perceives that I'm approaching him to pet him, he stays. He's not like the cliche of his species, he doesn't bite or even nip; he's not territorial - at least with me; when I try to grab him away...

Title pretty much says it all. My tiel is a seed junkie and I'm working on getting him to try veggies and fruits. I have given him peas, carrots, apples, cauliflower, and celery so far. He instead pecks at the dried poop in his cage instead of eating his veggies..he hasn't eaten any in 2 days...
