Can You Breed Brother And Sister Chickens With Each Other?

The number of people keeping backyard chickens has been increasing recently due to people wanting a cheap source of fresh, organic eggs.

Many people who initially started out with a small number of chickens have really gotten into keeping backyard chickens and scaled everything up.

This has resulted in a number of questions being asked about keeping backyard chickens each month from the community so we have decided to start answering as many of them as possible.

One question that we have seen people asking about their chickens is if they can breed brother and sister chickens without issue.

The number of people asking about this as well as breeding half sibling chickens as been increasing over the last couple of months so we wanted to publish this article to try and help our readers in this situation.

Can You Breed Brother And Sister Chickens?

The answer to this question is a bit tricky and it really depends on what you are trying to achieve by breeding brother and sister chickens.

If you are just looking to have a few baby chicks around the yard, then there is no harm in breeding brother and sister chickens together.

However, if you are looking to produce high-quality offspring that are going to be used for show or for breeding purposes, then you will want to avoid breeding brother and sister chickens together.

The reason for this is that when you breed closely related chickens together, there is a higher chance of them inheriting genetic defects from their parents.

These defects can range from being minor and not affecting the chicken’s health at all to being major and potentially deadly.

So, if you are looking to produce high-quality offspring, it is best to avoid breeding brother and sister chickens together.

Can You Minimize Genetic Defects?

If you do decide to breed brother and sister chickens together, there are a few things that you can do to minimize the risk of your chicks inheriting any genetic defects.

Breed Healthy Stock

The first thing that you can do is to make sure that you are only breeding chickens that are from healthy stock.

This means that you should only breed chickens that come from parents that were healthy and did not have any genetic defects.

You should also avoid breeding any chickens that have already shown signs of genetic defects.

Breed The Strongest Chickens

The second thing that you can do is to only breed the healthiest and strongest chickens from each generation.

This means that you should not breed any chickens that are sickly or have any physical defects.

Only breed the healthiest and strongest chickens from each generation and this will help to reduce the chances of your chicks inheriting any genetic defects.

Avoid Continuous Inbreeding

Another thing that you can do to reduce the chances of your chicks inheriting any genetic defects is to avoid continuous inbreeding.

Continuous inbreeding is when you breed brother and sister chickens together for multiple generations.

This should be avoided as it can lead to a build-up of genetic defects in the offspring.

Is Breeding Half Sibling Chickens Ok?

Breeding half sibling chickens with each other is usually a better option than breeding full siblings with each other due to there being more genetic diversity available for the offspring.

It is far more common for people to breed half sibling chickens with each other rather than full sibling chickens.

This will can produce much healthier off-spring for most purposes but if you are just wanting to increase the number of chickens you have producing eggs then you should be fine breeding half siblings.

Will The Chicks of Breeding Brother And Sister Chickens Be Ok?

The vast majority of chicks that are produced from breeding brother and sister chickens together will be just fine and have no health defects.

However, there is always a chance that some of the chicks will inherit genetic defects from their parents even if their parents are not related.

Common issues with chicks can include the chick bleeding after hatching, the chick being lethargic, and the chick hatching with its intestines hanging out.

Although there is no reliable data that has been collected at scale, it would seem that there is around an equal chance for chicks that are produced from non-related parents and related parents to have these issues.

Logic would suggest that the chances of the chicks having genetic defects from related parents after many generations will increase and this is why we would recommend against continuously breeding brother and sister parents from multiple egg clutches over and over again.

Will The Eggs Of Breeding Brother And Sister Chickens Be Ok?

Many people who are planning their backyard chicken setup think that you have to actually breed chickens to have them lay but this is not the case.

You only need to breed the chickens for fertile eggs that can hatch and produce chicks.

Most types of chickens will be able to consistently produce eggs that are good to be eaten.

Due to this, there is no need to worry about the condition of the eggs as you don’t need to breed a chicken with her brother to get her to lay.

How To Avoid Inbreeding In Chickens!

The easiest way to avoid inbreeding chickens is to keep the siblings apart from each other.

Multiple roosts and chicken runs should be able to do this for you but we know that not everyone will have the space or the budget available to do this.

Due to the low prices of chickens or fertile eggs right now, it is usually very cheap and easy to just get a new chicken for your setup that is not related to any of your current stock anyway.
