No. It is hard enough to sex a day old chick. There is only one way see into an egg and that is by candling. Candling only shows dark shadows and no definition. There is absolutely no way to tell from shadows what sex a chick is.
No. The size and shape of an egg does not determine the gender of the potential chick inside the egg. There is absolutely no way to determine gender until the embryo is fully formed and hatched.
Yes, by examining the DNA of the cell, you will be able to determine if the donor was male (XY) or female (XX) based on the sex chromosomes. You will not be able to determine the sex of the donor by the appearance of the cell - the only way is to determine what sex chromosomes are present. Unless the cell is a sex cell, in which case sperm cells are easily distinguished from ovum/eggs.
The same way you eat an ostrich egg.
No. UPDATE: Yes, in way you can actually tell, because roosters don't lay eggs and therefore don't sit on nests. So when your chicken starts laying eggs, you know its a "girl" (girl chicken= a chicken or hen, boy chicken = a rooster or cock) Roosters also crow and their combs and tail are most of the time (depends on the breed) bigger.
Ground rattlers are a type of snake. Their eggs look like chicken eggs in a way because they are round and white. However, they are smaller than chicken eggs.
Its just the way they are
There is no way to stop a chicken from laying eggs; It's nature's way.
By the size, the way it looks and the way it acts i know this isnt really specific but females are usually bigger because they have to carry eggs
by cracking them open that's the only way
Something that was nearly a chicken. The way natural selection works, is through gradual change due to mutations in reproduction, so the parent of the first chicken eggs wasn't a chicken, but a bird that was almost a chicken that laid mutated eggs.
The eggs are fertilised inside the hen, and then laid.
It is not good if your chicken is eating its own eggs but it should not effect the taste of the meat or eggs. If your chicken is eating its eggs the only way to stop it is to check for eggs more often and try to make sure you pick up the eggs as soon as possible.
