What do I feed my queen Pogonomyrmex Californicus during her founding stage she made her hole but not sure wether she has layer eggs or not but she often goes out I think to search for food I placed grass seeds in a corner but she hasent even touched them it's been a week

If she's a semi-claustral queen she probably wants either honey/sugar water or more likely insects (try fruit flies or mealworm parts if you have or a cricket/grasshopper leg, but do NOT feed insects that could have had contact with pesticides, you don't want to poison your queen).
