As a mother bird, you must gather worms and insects to feed your chicks. The won't eat until they're hungry. They die of hunger fairly quickly after demanding to eat. You can only carry one bite at a time. You have two or more chicks. Watch out for predators who are after you as you go hunting for your own prey.
