It's not just the female who only has one opening -- the male has it too -- in both it's called a cloaca.
In most birds, including domestic chickens, the male has no penis (which explains why Flossy Mae never found one!). The sperm is transferred during mating by the two cloacas pressing together.
The hen lays eggs in the nest, visiting it for a few minutes each day to do this. If you keep taking them away, she'll carry on laying, but if you let the nest fill up, after a couple of weeks she'll go broody and sit all the time (if we want a broody amongst our hens, we put lots of golf balls in the nest -- they can't resist a nest-full!).
When broody, she'll fluff up her feathers, squawk and growl if you disturb her. Often she's almost unable to stand, and will desperately try to return to the nest if taken away. She'll also lose a patch of feathers on her belly -- this "brood patch" is used to keep the eggs warm. Most domestic hens are not fussy about what eggs they sit on, and will happily hatch eggs of other hens, or even of other species such as pheasants, ducks, geese or turkeys.
The sitting hen hardly eats or drinks, and can lose a lot of weight. If fertile, the eggs hatch after 21 days of sitting (geese and turkeys are 28 days). They don't start developing until the hen sits, so they all hatch together, even though they were laid over a span of a couple of weeks.
The hen will look after the chicks for several weeks, keeping them warm when they need it, and showing them food. She does not feed them directly much (if at all --turkeys do this a bit though). She will also guard them very bravely, and will often chase off a human, dog, cat or rat who comes near. To start with she will take them back to the nest at night.
Because hens don't lay while broody, broodiness has been bred out of many egg-laying breeds. The eggs of these breeds have to be hatched under a hen of a different breed, or in an artificial incubator. Most commercial chickens are hatched in an incubator anyway.
Some male birds do have a penis. These include waterfowl (geese and ducks), and the ostrich family.

Chicken reproduces sexually, the males are responsible in copulating. On the other hand, the female laid eggs and hatch on it. That's the nature of it! However, advance technology on poultry industry have used laying mash to produced more in numbers with the aid of incubators.

The rooster fertilizes the eggs that she lays by climbing on her back and grabbing her comb and shaking her.She then sets on her eggs for a time I don't remember how long and then the chicks hatch.We had chickens when I was growing up and and I saw this a lot.I don't know if he has sexual organs or not.I have killed and cleaned many a bird and never found one.So I assumed the pecking her comb was what fertilized her eggs.

They have themselves some chicken sex.
More scientifically, chickens reproduce sexually, though the female chicken has only one opening, it serves for reproduction as well as waste..
