So...I should have kept on top of things better. My daughter is usually the one taking care of the chicks, and she just informed me at 9pm that we're out of chick starter. Completely out. Of course the store is closed, so I can't get any more tonight. I can go first thing in the morning - they open at 8am.
Until then, what should I do? She says they still had food some this afternoon, but they ate it. I have layer feed, scratch, mealworms, and fruit/veggie scraps. The chicks are about 4.5 weeks old.
