Chickens would rather eat from my hands than what is on the floor/their feeder?

I figure it's that they trust me more or it's more interesting when it's coming from me but... I just find it funny how if I have say a romaine lettuce heart that I'm holding, and another heart on the floor they all just fight over what I'm holding instead. Or they'd rather eat pellets that are in my hand over their feeder... It's too cute tbh.
