If they are being hand-reared, a chick from the egg will need to be fed every 60-90 minutes for around 16 hours per day. Once the chick is a few days old (depending on species), feeding frequency can be extended to every 2 hours. Quantity is at least as important as frequency - they are easily over-fed. Dehydration, rather than starvation is also a major problem with people unused to hand-rearing birds.

Most likely because the nest has been disturbed, or humans have been too close to it.
They need to have food when out of the shell. Scratch works well.
An alevin is a newly hatched fish, especially a salmon.
After the nits hatch, the louse must feed on blood within a day or die.
Ducks usually leave the nest just after all the eggs have hatched because the mother bird does not feed the chicks, they have to find food for themselves and to do this best they need to be on water. Thus the mother duck will take them out of the nest and to water immediately.
Newly hatched sultan fish are typically small in size and have translucent bodies with underdeveloped fins. They rely on yolk sacs for nutrition initially and are vulnerable to predation in the wild. They often stay close to cover and shoal together for protection.
Any bird you find on Antarctica is breeding there, because there are no land predators. However, some adult birds take newly hatched chicks to feed their own young. Otherwise, all sea birds find their food chain in salt water.
Birds, no birds, have breast nipples to feed their young. They rely on insects that the mothers mash up in their mouths and feed to their babies. When they are older and can fly, they will drink water and catch their own insects.

Hatchling spiders will feed on tiny insects. For example, the baby spiders in my collection feed on what are known as 'micro-crickets'. These are newly-hatched crickets about 2-3 millimetres in length. I gradually increase the size of the crickets as the spiderlings grow.
