I wouldn’t be worried as it’s still early days. Every hammie is different, mine took four days to (nervously) take a pumpkin seed from my hand. I’d keep trying each day when you know your hammie has been awake for a lil while with a yummy treat - mine would do anything for pumpkin or sunflower seeds.
Every time I’d put my hand in the cage he’d scurry in his tunnel but I’d stay quiet and still and hold the seed in my fingers. Eventually he plucked up the courage to take it. Don’t give up though! It’s early days and the taming process can be annoying and long, but it picks up quickly and is so so rewarding
