It takes 24 hours.
The yolk, which is called an oocyte is produced by the hens ovary in a process we call ovulation. As the yolk is released into the oviduct it is fertilized by sperm deposited by the rooster up to 10 days prior to the ovulation.
Fertilized or not, that yolk continues down the oviduct and is covered by the vitelline membrane, structural fibers and albumen in the magnus area of the oviduct.
As this forming egg continues it's travel down the oviduct it rotates continually within the spiraling tube (oviduct) and this movement twists the structural fibers forming rope like strands called chalazae. two of these chalazae anchor the yolk in the very center of the albumen.
As this egg gets closer to the end of the oviduct, the egg shell begins forming. Calcite is deposited around the albumen and yolk and in some breeds, bile ducts deposit color, which is why the egg can be white, brown or even green or blue.
Once this is all done, the egg is laid by the hen through the cloaca also known as the vent.
All this takes about 24 hours.
It will grow and develop until fully formed.
When the internal temperature is 160 degrees or over.
Cooking chicken is done by using a slightly lower temperature, and allowing a longer time to the chicken to be cooked fully through. Cooking at a high temp. will char the outside of the meat, and leave the inside uncooked.
To properly cook chicken for enchiladas, you can start by seasoning the chicken with salt, pepper, and any desired spices. Then, cook the chicken in a skillet until it is fully cooked and no longer pink inside. Once cooked, shred the chicken into small pieces and use it as a filling for your enchiladas.
You can reheat fully cooked smoked chicken in the oven on a low temperature. You can also reheat this type of chicken in the microwave.
A cooked chicken thigh is typically browned on the outside with juicy, tender meat on the inside. The skin may be crispy, and the meat should be fully cooked and no longer pink.
You can determine if chicken is fully cooked by using a meat thermometer to check that the internal temperature has reached 165F (74C).
You can determine if chicken is fully cooked by checking its color, texture, and juices. Fully cooked chicken should have no pink color, the juices should run clear, and the meat should be firm and not rubbery.
Not fully developed is partial formed.
Chicken tenders, like most other foods, should be fried at 425 degrees Fahrenheit. This temperature allows for fully cooking the food on the inside, while crisping up the outside.
Often the mortality rate of near hatch chicks is because of low humidity or high temperatures. Once the chick is fully formed inside the shell, moisture keeps it lubricated for movement within the shell case. The chick needs to move in order to complete its peeping or breaking of the shell and dry shell/low humidity is often the culprit. The first few hole made by the egg tooth allow air inside the shell but also increases the release of moisture so the humidity in the incubator should always be at least 65% or better for good hatch rates.
The recommended temperature for fully cooking chicken to ensure it is safe to eat is 165F (74C).
