Can Chickens Lay Eggs Without A Rooster?


Sharing is caring!

Can chickens lay eggs without a rooster? Yes! Healthy female chickens are able to lay eggs with or without a rooster in the flock. However, without a rooster, the eggs will not be fertilized, which means a chick will never develop.

Most hens begin laying eggs when they are about six moths old, though this will vary by breed. Hens that are mature enough to lay eggs do not need a rooster to do so. Healthy hens will lay eggs consistently for several years, never needing a rooster.

If you wish for your hens to be able to hatch eggs, then you will need a rooster in the flock. The rooster will fertilize the eggs and make them viable for incubating or allowing the broody hens to sit on them for hatching.

What’s The Difference Between Fertilized and Unfertilized Eggs?

While there are some minor differences in fertilized and unfertilized eggs, you will be glad to know that the nutrients, flavor and consistency is no different.

In order for a chick to develop in the egg, the egg needs to be incubated for 21 days. This can be done by a broody hen(the term “broody” refers to a hormonal shift in the hen that gives her the drive to sit on her eggs, keeping them warm and protecting them until they hatch), or this can be done with an incubator in your home or garage.

If you collect your eggs daily or every couple of days and store them in a cool place, like on your counter or fridge, then the embryo will not have a chance to mature.

Should I Keep A Rooster?

There are definitely pros and cons to keeping roosters. It’s a good idea to do some research and decide whether keeping a rooster is a good fit for you. Let’s get into the pros and cons of keeping roosters.

Pros To Keeping A Rooster

  • Probably the biggest pro to keeping roosters is their ability to protect the flock from predators. Roosters will fight to the death while protecting their hens. They will fight hawks, owls, small dogs, foxes and more.
  • Roosters sound an alert to warn the hens of the impending danger. It’s pretty remarkable to watch a rooster in action.
  • Roosters sometimes get a bad wrap because they can be aggressive towards humans. But it’s all apart of their make up, they have an innate responsibility to protect their flock.
  • Roosters are such great care takers, that they will even call over the hens if they find a stash of tasty treats; like grubs or something good in the compost pile. 
  • Roosters will also help to keep your flock growing, by fertilizing the eggs. If you have a nice well-rounded flock, then you will probably get a few “broody” hens in the spring time. If you allow these broody girls to set on their clutch of eggs for 21 days, you will have a new brood of chicks and therefore fresh egg-layers in the fall. And in my opinion, allowing a mama hen to raise the chicks is the best way to do it. I’m spoiled now and I hope I never have to brood chicks myself with heat lamps and such, it’s way too much work!

Cons To Keeping A Rooster

As you have learned in this post, you don’t need a rooster in order for the hens to be able to lay eggs. Roosters can be noisy, aggressive and since they will be fertilizing the eggs, you may end up with more chicks than you have space for(though you can curb this by collecting your eggs and not allowing hens to set on them).

  • Roosters can be noisy. Even if you enjoy the heralding “cock-a-doodle-dooo” as soon as the sun begins to rise, your neighbors may not and that could be an issue.
  • In many suburban and urban areas, roosters are not allowed at all, so keep that in mind. We are not allowed to keep roosters in our current neighborhood(but you better believe we will have one or two once we move to the new farm!)
  • Roosters can be aggressive. For the same reason that people keep roosters(protection), is also a reason people don’t keep them – they can be aggressive. And full-grown roosters have spurs on their feet that can really hurt. If you want to keep a rooster, it’s best to keep on top of training them, otherwise they will see you as a threat to the flock and attack when you least expect it.
  • Roosters are rough on hens. If you are going to keep roosters, it is important to keep a goo rooster to hen ratio. Too many roosters and not enough hens can cause overbreeding. The hens can start to lose feathers on their backs and get worn out physically. 10 hens to 1 rooster is a good ratio to keep.

To sum it up, there are many pros and cons to keeping roosters and there is no one right answer for everyone. I hope this information was helpful for you as you try to navigate whether or not you should keep a rooster on your farm or homestead.
