no - birds don't have a woumb. Mammals developed these things to hold their eggs inside their bodies until the eggs hatched. Lots of fish and quite a few reptiles do this too. The difference with mammals is the egg literally attaches itself to the wall of the woumb and forms a special structure known as a placenta. Mammal eggs don't have yolks and the placenta extracts nutrients from the mother's blood to feed the embryo. Chickens and humans both lay eggs, but when a human lays an egg, the woumb prepares itself for a potential pregnancy. The walls fill up with blood and grow much thicker. The chicken is only concerned with forming a shell around the egg. After mating the egg may or may not be fertilized. The chicken's egg is thousands of times the size of a human egg and consists almost entirely of an enormous yolk sack. Chicken eggs are eventually surrounded by a shell whether they are fertilized or not. A human egg is almost microscopic and has no yolk. In fact, the yolk forms after human eggs are fertilized. If human eggs are not fertilized, the uterus behaves much like a stage after a concert. Everything is torn down and the stage is cleared for the next act. The outer walls of the uterus begin to break down and peel away and this is what mensturation is. The chicken is more like a factory than a theatre. In the chicken, its assembly line is never dissassembled. It is always ready to process the next product.
BTW: the major reason all birds lay eggs is because it would be very hard to fly if one was pregnant. It would probably be quite dangerous as well.

Eggs at the instant are not hen classes. they're an ova, released interior a similar way that a human lady releases an ova each and each month. If the ova is fertilized it is going to mature right into a toddler. In human beings an unfertilized egg leaves the physique alongside with the wealthy tissue that has been arranged interior the form of fertilization. In a chink's case the unfertilized ova is eaten. there's a connection, nevertheless that is not technically a era, fetus, or abortion. It did have the skill of being a toddler, is the element some human beings try to make. "Why perform a little radical vegetarians sense the ought to lie?" Being which you're a thorough omnivore who feels the ought to lie oftentimes, you could probable answer this extra advantageous then i will.

A period is the menstrual cycle of a mammal, where the womb literally refreshes itself for the implantation of an ova...or egg. However an egg (ova) from a chicken is released daily and there are no menstrual cycles in birds. Most mammals undergo a 'heat' when they are ready to concieve...the scent or pheromones attract males for insemination... Some men clain that they can smell a woman that is in 'heat'....I don't believe we have this ability but as you know dogs and other animals do.

well considering the fact that the egg isn't fertile until the rooster is let in the chicken coupe. I would have to go with YES an egg is a chickens period... Hens can lay infertile eggs until the cows come home as soon as you bring in the "****" you have little baby chickens....

An egg is something that a chiken needs to shed even if its not fertilized. I know its not a period for sure, but I cant remember what it is that it sheds. I took animal science in school and that was years ago. It is not its period though.

Are you pro life or pro choice? It is essentially the same debate. I am not going to say what I think, you will get enough opinions anyway, but people are going to stand on both sides of the fence. It all boils down to opinion.
Funny thing is I have just been asked a pro choice, pro life question. I gave her a vague answer because this is one of just one of those questions. I know what you are thinking, COWARD

No. It's a chicken's offspring. That is if it was fertilized. Eventually it would crack open and a chick would come out.

yes and no, it is the menstuative equivalent and but not all eggs are fertile.
what is known as the speck in cooking is the fertile part of an unfertilised egg, this is not present in all eggs.
(i have cracked over 100,000 eggs in my life thus far ;)
