No, not all chicken eggs are fertilized. Most mass-produced eggs from battery farm operations are not fertilized, as the hens live their whole lives without seeing a rooster.
Roosters must mate with the female chickens in order for the hens to produce fertilized eggs. No rooster, no fertilization.
Hens are able to produce fertilized eggs for 1-2 weeks from one conjugal encounter with a rooster, but it takes a few days for the rooster's sperm to begin fertilizing her eggs.

∙ 15y agoEggs do not have to be fertilized by a rooster if you are going to eat them.... A hen will continously lay eggs without a rooster present. However, if you wish to hatch baby chicks, then yes, they must be fertilized to hatch.

∙ 12y agohens and ducks obviously lay eggs that have not been fertilized, as well as eggs that have. the eggs that have been fertilized will eventually become chicks. from the best of my knowledge, other birds do not lay eggs unless they have been fertilized through sexual reproduction. so yes, bird's eggs must be fertilized before they will become chicks.

∙ 13y agono, only fetilized eggs can hatch" is incorrect. there are a number of recorded cases of parthenogenisis in domestic chicken and turkey farms. (chick has 100% of mothers genes)

∙ 11y agoYes. Like all birds, chickens reproduce sexually. If a chicken has not been fertilized then the eggs will contain no embryo.

Does a chicken egg have to be fertilized by a male chicken to make a chick?
They lay eggs daily, but if you want chicks you have to have a male to fertilize the eggs.
Do buff cochin's lay many eggs?
Cochin's are considered "fair" layers. You can reasonably expect 3 to 5 small brown eggs per week out of a buff. Cochin's are popular show birds and excellent mothers/brooders. Robust and hardy the Cochin is peaceful and easy to handle. They make excellent foster moms to incubated chicks. Free range birds can get foot problems as mud and snow will cling to the feathers around the feet. Wonderful birds even if they don't produce that many eggs.
Should a setting hen be isolated from the rest of the flock?
Yes. A setting hen should be isolated from the rest of the flock for the safety of the eggs, resulting chicks, and the brood hen, herself. Chicks have been successfully hatched without taking this precaution, but many who've done it have had problems resulting in dead or injured birds and low hatch rates. Results like these make it not worth the risk.
How long does it take a hen to be pregnant before she lays the egg?
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.
Why do birds lay eggs in nest?
Cuckoos lay their eggs in the nests of other birds so that the effort of raising them is done by other birds. When they hatch, the cuckoo chicks tip any other chicks out of the nest, so that they receive all the attention and food.
Why do birds make their nests in trees?
It keeps the eggs and chicks away from ground dwelling predators.
Why do birds have eggs instead of live birth?
That is an evolutionary question. The simple answer is generally considered to be that eggs weight less than fully hatched chicks, and therefore it would make it difficult for a mother bird to fly if she were carrying five chicks instead of five eggs. As for flightless birds, if they evolved from birds of flight, then there is no evolutionary reason that they would have become viviparous.

Can you use local free range eggs in a restaurant?
Certainly. As long as you get them from a reliable source that sells you fresh eggs, not old eggs, free range eggs are great, and much healthier than store-bought eggs. If the hens are fed camelina seed, the eggs will even have Omega fatty acids in them, which will add an even more appealing touch for customers. It doesn't make any difference if the eggs are fertilized, although you may want to talk to your customers about that, if they are squeamish about it, and assure them that fresh, fertilized eggs do NOT have chicks growing in them, and taste exactly the same.
