EDIT: These chicks moved away from me to a nice farm and to their new owner when they were three weeks old. The new owner, a 13 year old responsible farm boy, feed them high quality chick feed, kept them under heat lamps for several weeks, took them out by hand and kept an eye on them as they explored the world around the barn and watched them eat grass/insects, and he sent me pictures and updates until they were fully adult. It turns out they were both female, and they were introduced to the flock of hens they had with great success.

Story:
This is my new baby chickens that I hatched a few days ago in my new incubator. They are named, yeah, you guessed it right, Jiraiya and Sai, named after two characters from the anime Naruto.

They are hatched from ordinary food eggs, straight from my fridge and bought in an ordinary store, out of the seven eggs I put in the incubator only two were fertilized. I am really glad that they made it all through their development, despite of everything they have had against them.
They love sleeping in my hands, and they enjoy human company. I have already found a good home for them since I can not keep them myself, even though the rules for this apartment states that I can if they don't disturb my neighbors, I think it's best for them to live on a farm, being able to go outside and be with other hens and roosters.

They will stay 2-3 weeks with me, until they are strong enough to move to a new environment safely and have put on some feathers :)

- NOTE - You will NEVER find a fetus or a baby chick in a food egg from the store, HOWEVER read this please:
This is how it works most of the time, in most places.
Some people have big hatcheries, where they hatch chickens that will go too the food industry and the egg industry. These two groups are genetically different from each other, they look different, grow differently, and work differently.
The broilers, the chickens breed for meat, get big and chunky really fast, but the egg laying industry chicks stay slim, they do however lay egg at a higher rate then the broilers parents do.
The broilers can be either gender, but the chicks that are sold to the egg laying industry have to be all female. Therefor the male chicks are identified at a young age and disposed of, a small percent used for cat and dog food, but most of them just get disposed of.
The hen chicks, as they reach a egg laying productive age, are sold to the egg industry, HOWEVER, a few male chicks sometimes get past the identification process, leaving maybe one rooster in a room of 600 hens. (he is one lucky guy I guess)
It is impossible to catch a white rooster among 600 white hens, because they are not used to humans close to them, so if you go in you have panicking hens running all over the place, and you can not find the rooster. Some rooms have 400-1200 hens in the same room, so catching one rooster in such a group is not possible.

YOU WILL MOST LIKELY NOT FIND A DEVELOPED FETUS IN A 'FOOD EGG'.

The reason for this is as follows: When the egg yolk releases inside the hen, and travels down through her to become an egg, sometimes a few drops of blood might come with it. The egg facility scans all eggs for this, and IF there would be a fetus in an egg, this would also be removed with the 'blod drop' eggs.

Anyone that have ever had a group of hens and a rooster and eaten the eggs have eaten fertilized eggs, it's just two egg cells instead of one, and is completely safe and will taste/look no different from an unfertilized egg.

I am glad that these two made it out ok, and I love them so much already. I hope and pray that their parents lived a decent life and that they die a not so horrible death.
