It depends on the species of bird that laid it, how cold for how long and how far incubated the egg is, but eggs can be left to cool for surprisingly long periods if incubated - in some species it can be days, but most it can be an hour or so. Under ideal storage conditions, fertile eggs from many species of bird will remain viable, if not incubated previously, for a month.
cold blooded come from the eggs, warm blooded comes from privates
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
A duck will sometimes sit on unfertilized eggs. Usually, after a while the duck will come to realize that the eggs are not going to hatch and she will give up and move on.
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
Fertilized fish eggs.
Male stick insects can be produced from fertilized eggs, whereas females can come from both fertilized and unfertilized eggs.
It usually takes goldfish fry about 5-6 days to hatch out of the egg once fertilized. The egg-stage's length can range greatly depending on what temperature the fry are kept in. With fish, usually the higher the temperature the faster the eggs will hatch and vice versa.
Chicken eggs require 21 days at 101F to hatch. When trying to hatch chicken eggs, give them a few extra days before throwing out eggs that have not hatched as they may have been cold and needed a day or so to come up to incubation temperature.
Only if they are fertilized and incubated. Most eggs are not fertilized and therefore will never become a chick.
Stem cells come from newly fertilized eggs because those eggs divide and evolve into more specialized cells.
Its the food that a fertilized ovum eats in the early stages of pregnancy if the ovum isn't fertilized then it leaks out because you don't need it
I am pretty sure eggs will only come out of a female ants body if they are fertilized but since I'm probably wrong about that I don't think the eggs would be able to hatch without fetilization so nothing I guess? I hope that helps you :)
