False. Only single-celled creatures like amebas reproduce by division.

Turkeys reproduce in a manner similar to some other animals. The female produces an egg which if fertilized can result in a baby chick. The true egg, the part that develops into the embryo, is located on the egg yolk. The yolk begins to develop in the ovary and after 10-12 days of development, ovulation occurs. If the female has been mating with a male, sperm will be present and fertilization can occur. The male chicken does not have a penis and therefore there is no penetration of the female reproductive tract at the time of mating. Instead the female inverts the cloaca (site of the common junction of the reproductive and digestive systems) which comes in contact with the male’s inverted cloaca and receives the sperm. The cloaca is then drawn back into the hen’s body and the sperm are captured. They then begin the journey up the length of the reproductive system. The sperm live inside the female reproductive system and each time an ovulation occurs (every 24-26 hours in good egg producers) the egg can become fertile. This process continues and matings at 7 - 10 day intervals are necessary to maintain fertility. After fertilization occurs the egg albumen, shell membranes, and shell are added to complete the egg formation process. The chicken usually lays the egg about 24 hours after ovulation.

You heard right, compadre. Parthenogenesis--reproduction without benefit of sex--occurs spontaneously in a handful of species, most of them fairly simple but some surprisingly complex. The turkey is the foremost example of the latter group, with the virgin birth rate in some breeds approaching 40 percent. Parthenogenesis also occurs in some lizards. The New Mexico whiptail lizard, for example, is a nearly all-female species that reproduces almost exclusively by parthenogenesis, males occurring only rarely. A few years ago a biologist was startled to discover that a snake he'd raised from its second day of life had produced a litter, even though it had never been in the company of a male. Yow, he realized, snakes too can reproduce parthenogenetically! However, as a matter of practical advice, while the virgin birth explanation may satisfy a scientist, I still wouldn't try it with Dad.
Various explanations have been offered for parthenogenesis. It's said that virgin birth becomes more frequent in turkeys if the female is exposed to semen having a low sperm count--second-rate goods, in other words, which may incline the female to think she'd be better off seeing what she could whip up on her own. An alternative thesis, proposed by myself, is that parthenogenesis occurs chiefly in critters too homely for sex to be practical. I mean really, a turkey, with the wattles and all? Or a greenhouse slug, also suspected of propagating itself parthenogenetically? Say I'm a slug and I spot a member of the opposite sex. You figure I'm thinking, "Boy, wouldja get a load of the cloaca on that one"? Uh-uh. More like, "No way am I having sex with that."
Strange though it may seem, parthenogenesis is a phenomenon highly prized by animal breeding experts, because like cloning it would obviate the messy unpredictability of sex and instead produce exact replicas of prize specimens. Useful as virgin birth might be in poultry, it would be even more so in mammals, where you could put the production of grade-A heifers and the like on even more of an assembly line basis than it is already. So far, however, this goal remains but a distant dream, owing to certain peculiarities of the mammalian genome. Fine by me. Think of all the delightful aspects of the reproductive process: menstruation, pregnancy, labor. And the part we're trying to eliminate is sex?

Turkeys can reproduce without sex. My family had a Turkey farm when i was growing up, we used to artificially inseminate the Turkeys so no, they didn't have sex lol

False. It takes two turkeys of opposite sex to make fertile eggs.

Half true, most commertial turkey have so much breast that they find sex diffcult so the turkey breeders artifically inseminate the hens with the tom's semen. Sex by mail - sortta.

Where did that come from? I'm not sure that a male turkey mounting a female can be described as sex, but they do he does have to inseminate her.

True, 1 in 277 turkey eggs is already fertilized...it's a clone of it's mother.. don't ask me why, it just is. Best wishes

Definitely true, although rare. I remember my poultry professor in college telling this funny story about the scientist who discovered this phonomenon, although I can not for the life of me remember the story.
