how are chicken eggs fertalised?

Question

i dont understand how a chicken knows when its egg is going to be a little yellow bird or a fried egg sandwhich filler - cuase they seem to lay eggs regardless of the exitence of cocks

Answer 1

A chicken egg is fertilized in the chicken, before it is laid. Not every egg is fertilized. Hens will lay eggs as long as there is a rooster around. He does not necessarily have to fertilize the egg for the hen to lay it. If you need something more graphic than that, I would suggest you do a web search in chickens and breeding.

Answer 2

The egg cannot be fertilized if there are no roosters penned up with the hen. Even if the egg is fertile, a baby chick won't develop inside the egg if the egg isn't kept withing a certain temperature range most of the time. To tell if the egg will devolop into a chick, chicken breeders candle the egg (shine a light through it) to see how the egg is developing inside.

Then hen doesn't know if the egg will hatch or not. They will even sit on a plastic egg.

Answer 3

Well if one eats eggs straight out of the yard, as we call it in the country yard eggs, there's a chance of you consuming a fertilized egg. How to tell? There's a white blotch in the yolk. For the hen to know, she doesn't, it's intinct to sit on the eggs fertilized or not. My grandmother, back in the day, and my brother who currently went back to raising chickens allow a hen to sit so that there will be a new generation of birds. Other than that; they would be out picking up eggs in the yard in the hen house and using them for frying or baking.


addendum: the ones you get out of the store; no rooster no fertilization.

Answer 4

A hen laying eggs is like a woman's monthly cycle, they simply release an egg regardless if it's fertilized or not, it's just something they do naturally.
