I often hand fed worms and greens. Cooper would go after crickets on his own and dig into his salad bowl on his own though so the hand feeding was just for some interaction.
I do not hand feed Gizmo. I place her in a separate tote for feedings. The crickets were getting too good at hiding in her Vivarium. This helps her tank stay cleaner IMO. I do however put her veggies in her viv.
i handfeed Hoss all the time. Veggies, worms, crickets, etc. I'm not afraid to touch them and it makes me feel a closer bond to my beardies. That's the cool thing about having a reptile instead of a cat or dog. You can literally hand feed them everything instead of just throwing it in a bowl and expecting them to eat throughout the day.
I mix it up; i try not to do it constantly so she gets too lazy w/feeding but i'll let a roach crawl on me and let her eat it from my hand.
Usually i'll hand-feed her treats if she's being picky
