When do chicks hatch?

Answer 1

25-35 days

Answer 2

If the egg has been fertilized a tiny white spot on the yolk of the egg will soon become red with blood as the embryo starts to develop. For a chicken, it takes 21 days from the time the egg is laid to the time the chick hatches.

The embryo needs food, water and oxygen to grow, so thin red blood vessels spread out from this spot over the yolk and then all around the inside of the shell. The yolk provides most of the food, the albumen (white part) provides more protein and water and oxygen passes through the shell and the membranes. During the last few days the chick inside the egg begins to breathe with its lungs for the first time. To do this it needs an air supply inside the egg shell. At the big round end of the egg there is an air space. The chick makes a hole in this air space so that it can now breathe. The chick also peeps or calls to the hen through the shell. The hen then knows that the egg will soon hatch.

To escape from the egg the chick has a special point on its beak called an egg tooth. This egg tooth breaks holes in a circle all around the shell and the chick hatches. Here is a link to see actual pictures of this process.

Answer 3

The gestation period for a chicken egg is 21 days - whether under a hen or in an incubator. For a more complete answer to the question, see the question and answer "How long does it take for eggs to hatch when a chicken is sitting on them?"

Answer 4

Most breeders start the 21 day incubation in the early spring. While warmer climate areas can produce a hatch all year long, in northern climates the winters are far too cold to properly raise a clutch unless they are in a heated building. March is often a good month to set for artificial incubation.

Answer 5

It all starts in the egg. They are born withthose fluffy feathers and by day one there true feathers start to grow. Think of it like any other animal with feathers or hair. They are born with a little (or some, or a lot) and it slowly gets replaced. Most animals "shed" some after birth.

Answer 6

When the baby chicken is fully developed and ready to pop out.

Answer 7

21 days from start of incubation. Once the proper temperature and humidity is applied either by a broody hen or artificial means, the eggs will hatch in 21 days.

Answer 8

it takes about 21 days for a chick to hatch

Answer 9

After 21 days of incubation.
