How Do Chickens Mate? (Explained, Facts and Answers)

How Do Chickens Mate

As the days get longer and brighter and the temperatures begin to rise, the flock will start to stir in preparation for the mating season. But how do chickens mate?

The completed mating process in chickens is a culmination of a sequence of behaviors. The rooster initiates mating by exhibiting courtship behavior (although some roosters skip courtship altogether and get straight down to mating), which may include:

  • Tid-bitting – where the rooster finds a tasty morsel and calls over the chosen hen to inspect it. This behavior may not directly lead to mating at that time, but the hen will remember; he’s creating an impression.
  • Courtly rooster dance – this involves the rooster dropping one wing to the ground as he dances around his chosen hen, showing his interest.

To mate, a rooster mounts a hen, and standing on her back, he proceeds to lower his cloaca (vent) and the hen inverts her own cloaca to meet with his. No penetration occurs, but the sperm packet that is released by the rooster is taken into the hen’s cloaca or vent. The sperm then finds its way to the infundibulum where it awaits the release of an ovum.

When a hen finds a rooster that she deems worthy, she’ll go into a squatting position (by dipping her head and body and spreading her wings slightly) to signal submissiveness to the rooster. The rooster will mount her and begin treading to find his balance. He will also grab her comb, neck feathers, or head to steady himself further.

Once the rooster is well positioned, he will dip his tail down and to the side of the hen’s tail and deliver what is known as a cloacal kiss – this simply means their cloacas touch. A rooster doesn’t have a penis, just a tiny bump called a papilla that is found inside his cloaca. There is no penetration – instead, she will lean forward while he is leaning slightly backward so that the cloacas touch.

Once this happens, the rooster’s cloaca will deliver the sperm package to the hen whose cloaca is turned out to receive it. The sperm will travel up the reproductive tract. A sperm package contains anywhere between 100 million to 5 billion sperm. The sperm need to travel up to the waiting eggs.

However, not all sperm will make the journey – some will be stored in little pockets located within the walls of the oviduct. This reserve sperm is viable for 4-5 days and is capable of fertilizing successive eggs.

Does It Hurt Chickens to Mate?

Sometimes roosters can be a little rough when mating with hens. However, in most cases the damage that is endured is thankfully minor, such as feather loss and breakage.

Loss of feathers and red bald spots are an indication that the hen is a favorite with the roosters. Often, she will develop a small bald area on the top of her head just behind the comb (this is usually where the rooster grabs her feathers)

The area that usually suffers the most damage is the back, where the rooster’s claws can rake over the feathers and skin, sometimes resulting in skin abrasions.

Occasionally, if there are other roosters also vying for the hen’s attention, there may be some significant wounds inflicted among them. In extreme cases, combs can be ripped and will bleed profusely.

What Age Do Chickens Mate?

Starting at about 4 to 5 months, young roosters reach sexual maturity and start producing sperm. This is usually when they’ll begin to seek mates. On the other hand, many hens start to lay eggs at around 18 to 21 weeks of age. If your hens are laying eggs, it’s an indication that they are ready to be mated.

What Time of Year Do Chickens Mate?

Roosters think about mating with hens just about all year round – it’s in their instincts to carry on the breed. That being said, the behaviors associated with mating tend to ramp up in the springtime, and courtship activities are on full display much more frequently than in the cooler months.

How Often Do Chickens Mate?

Roosters tend to want to mate with hens as often as possible. In the mating season a rooster can mate anywhere between 10-30 times per day, depending on his enthusiasm and ability.

How Long Does It Take for Chickens to Mate?

On average, chickens mate for less than a minute. However, fertilization may not happen right away. The duration it takes for fertilization to happen can range from a one-off meeting to around 3-7 days on average.

Do Chickens Mate for Life?

Chickens don’t pair for life. Roosters usually mate with multiple hens, sometimes within the same day. Hens on the other hand may also mate with more than one rooster. They can even store sperm from multiple roosters and also eject sperm that she deems unworthy.

Will Different Breeds of Chickens Mate?

In most cases, different breeds of chickens can successfully mate. There are no problems that arise from hatching mixed breed chickens or incubating the eggs yourself. In fact, if you have a rooster in your flock, he will try to breed all your hens, regardless of size or breed. It can be interesting to hatch mixed eggs because the end result will always be a mystery. Just keep in mind that you may end up with some unwanted traits or behaviors as a result of this breeding.

Will Ducks and Chickens Mate?

Simply put, ducks and chickens will not successfully mate. There are significant duck and chicken differences that make a duck/chicken hybrid next to impossible:

  • Male ducks, or drakes, have external sex organs
  • Hens have internal sex organs that are not designed to be penetrated
  • The mating rituals of ducks and chickens are different

Furthermore, there are no scientifically documented cases of duck/chicken hybrids.

Can Chickens Mate with Their Siblings?

You can breed sibling chickens. It’s safe to mate brother and sister chickens for at least a few generations, but the issue is that you will be merely reassembling the genes of the parent, so unless you intend to do this, it is probably best to steer clear of this. Additionally, too much in-breeding can affect the fertility or hatchability of chickens.
