How Long Does it take After the hen lay and hatched one chick how much longer does for her to other?

The time it takes for a hen to hatch all of her chicks after the first one hatches can vary depending on the species of hen and the size of the clutch. In general, it takes about 24 to 48 hours for all of the chicks in a clutch to hatch.

For example, chickens typically hatch within 21 days of the hen beginning to sit on her eggs. The first chick may hatch anywhere from 19 to 21 days, with the remaining chicks hatching over the next 24 to 48 hours.

Ducks, on the other hand, typically hatch within 28 days of the hen beginning to sit on her eggs. The first duckling may hatch anywhere from 26 to 28 days, with the remaining ducklings hatching over the next 24 to 48 hours.

It is important to note that these are just general guidelines. The actual time it takes for all of the chicks in a clutch to hatch can vary depending on a number of factors, including the individual hen, the temperature and humidity of the environment, and the size of the eggs.
