How long does it take a hen to be pregnant before she lays the egg?

Answer 1

Hens lay approximately 5 eggs per 7 day week. Sperm from a rooster is stored in the hen's oviduct for up to 10 days, so after just a single successful mating many fertilized eggs can be laid. Depending on when the hen's last egg was laid, the next egg laid after the hen was mated will most likely be fertile.

A rooster is necessary to have fertilized eggs, but a hen will lay eggs even if no rooster is present.

Incubation time for fertilized eggs is 21 days. Days 1-18 require an internal temperature of 99.5 F and a humidity of 50-60%. Days 18-21 require an internal temp of 99.5 and a humidity of 70-80%. Eggs must be turned 3 times a day during incubation to ensure that the embryo doesn't stick to the inside of the shell, but DO NOT turn during the last three days as the chicks are trying to orient themselves for hatching.

Answer 2

Hens don't get "pregnant" in the same sense that other animals do. They either produce viable eggs or they don't but produce eggs they will. If a hen has been mounted by a rooster she will produce fertilized eggs for up to 10 days proceeding the encounter. Even when they produce a viable egg, they must brood that egg in order to produce a chick and they often do not bother.

Answer 3

In most breeds an egg is produced every 24 hours. This varies due to breed and condition of the hen. Older birds produce less often as do birds in molt.

Answer 4

The hen is not pregnant, she has been fertilized.

It only takes one mating and one day for her to have fertile eggs to lay.

Answer 5

It takes 4-5 months for hens to lay fertile eggs. Make sure you have a rooster or they won't be fertile.
