Because that is what the babies inside the egg eat as they are forming
They eat, or absorb, the yolk of the egg.
Egg yolk color of free range chickens can vary depending on their diet at the time. The more they eat green, orange, or yellow produce, the deeper orange the egg yolk will be. Egg yolk color can be dark orange but a black yolk means you have a spoiled egg.
I broke the egg there was no yolk and I mixed it with the food what happens if we eat the food
No, because the hens food determines what color yolk is in the egg. When a hen has a rice based diet the yolk will be light yellow?
Yes. The starch in egg yolk is made to act as an enzyme. So next time when you eat an egg remember that the yellow "yolk" part of the egg actually contains more fat than the white soft part.
Yes, bird's eggs will always have a yolk, for example, the eggs that we eat has a yolk and the chicken that layed the egg is not mated.
The yolk of the egg is the "food" for the growing embryo. When the duckling emerges from the egg the yolk has been all used up.
The yolk of the egg contains cholesterol. That is why people put on a low cholesterol diet are advised to eat egg white or egg beaters and avoid the yolk.
I am assuming the egg was boiled. If the egg was boiled and peeled and a dark or grey coating was apparent surrounding the yolk, yes it is safe to eat. The discolouration is from iron and sulfur reacting to heat.
the yolk! yolk
Nothing, it gets its nutrition from the white and the yolk already in the egg.
