I'd keep the sunflower seeds as special treats or rewards for doing something. Like training her to stand on a scale so you can keep track of her weight - if Hazel stands on it long enough for you to get her weight in grams, then she gets s sunflower seed. Being a gcc, once she's figured that out you might just find that she'll sit on the scale whenever she sees it just to try and get a treat.
And where are my manners, Hazel is a beautiful little girl. Congratulations on your new family member.
