No, unfortunately ther are no signs that an egg has been fertilised, it is not until the fertilised egg reaches the uterus and implants there that there are any detectable changes. Your body will then produce hcg (human chorionic gonadotrophin), a hormone which is produced to sustAI
no because the egg should have been fertilized , a period is when the egg hasn't been fertilized and needs to leave the body
The Farmer must "candle" the egg. Candling is shinning a bright light into the egg to see if the egg has been fertilized and if any changes are taking place inside the shell.
When its just fresh there's no telling. After the hen has been sitting on it or has been in an incubator you can tell be holding it against a bright light (you can see blood veins in the egg) or put it in water; a fertilized egg will float, and a non fertilized egg will sick. A spoiled/ rotten egg will float as well, but it will be quiet old when that happens.
You can't tell if it's fertile or not based on its weight. The same amount of stuff goes into the egg regardless if it's been fertilized or not.
yes
zygote
The most immediate external effect of an egg being fertilized, is that a change occurs in the egg such that it either repels all other sperm, or at least is no longer accessible to them.
zygote
It is necessary for an egg to be fertilized so the egg can hatch.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
Yes, a zygote is a fertilized egg.
Once hens are of a certain age, they will produce eggs. If you want an unfertilized egg, don't put the hen with a rooster. Depending on the breed, she will give you 1-6 eggs per week. If you don't have a nest box for her, she will make a nest on the ground. If you want fertilized eggs, place a rooster with the hen, make sure the rooster knows his job, and the next day you may have a fertilized egg. There is a way to tell if the egg has been fertilized once it's cracked open, but through the shell, you can't tell until the egg is incubated and the chick starts to develop.
