What Does it Mean to Cull a Chicken? (The Complete Guide You Need)

Hey there fellow chicken keepers! Today I’m tackling a topic that many of us find difficult but necessary to discuss – culling chickens. When I first started raising my backyard flock I had no idea what to expect when it came to making tough decisions about sick or unproductive birds. Let me tell ya, nothing prepares you for that first time!

So what does it mean to cull a chicken? Culling a chicken means selectively removing certain birds from your flock and humanely ending their lives. This is typically done to improve the overall health of the flock, prevent disease spread, or maintain productivity. It’s one of those necessary but challenging responsibilities that comes with raising poultry.

Why Would Someone Need to Cull a Chicken?

There are several reasons why you might need to cull a chicken from your flock

• Disease prevention – If a bird is showing signs of a contagious illness that could spread to the rest of your flock
• Serious injury – When a chicken has a severe injury that can’t be treated and is suffering
• Aggressive behavior – Particularly with roosters that become dangerous to humans or other chickens
• Decreased productivity – Commercial operations often cull older hens when egg production drops
• Sex selection – In the egg industry, male chicks are routinely culled since they can’t lay eggs

In commercial settings, particularly in the egg industry, culling is done on a massive scale. Male chicks are considered a “by-product” since they can’t lay eggs and aren’t economically viable to raise for meat compared to specially bred meat chickens.

When Is It Time to Cull a Chicken?

Knowing the right time to cull isn’t always clear-cut. Here’s what I’ve learned to look for:

• Noticeable drop in egg production (for commercial flocks)
• Frequent illness that doesn’t respond to treatment
• Decreased activity or isolation from the flock
• Inability to walk, eat, or drink normally
• Severe injuries that aren’t healing

I remember one of my older hens started isolating herself and barely moving around. After consulting with a vet, we discovered she had a chronic condition that couldn’t be treated. Making the decision to cull her was incredibly difficult, but it was necessary to prevent further suffering.

Common Methods of Culling Chickens

Warning: This section contains descriptions of methods used to euthanize chickens. If you find this kind of information disturbing, you might want to skip ahead.

There are several methods used for culling chickens, with varying degrees of humaneness:

Cervical Dislocation (Neck Breaking)

This is considered one of the most humane methods when done correctly. It involves a quick, firm motion to dislocate the chicken’s neck from its spine, resulting in immediate unconsciousness and rapid death. This method requires proper training and technique.

Carbon Dioxide (CO2) Method

When used correctly, carbon dioxide can cause chickens to lose consciousness painlessly before death. This method requires a controlled environment and proper concentration of CO2.

Decapitation

This involves severing the head with a sharp implement like a hatchet. While effective, it requires precision and can be difficult for many people to perform.

Maceration

Commonly used in the egg industry for day-old male chicks, this involves grinding the chicks in a high-speed grinder. While shocking to many, when performed correctly with proper equipment, it results in instant death.

Shooting

In some rural settings, shooting can be used when done by someone skilled enough to ensure immediate death with a properly placed shot.

The Most Humane Method for Backyard Flocks

From my experience and based on many sources, cervical dislocation using tree loppers is considered one of the most humane methods for backyard chicken keepers. Here’s why:

1. It’s quick and causes minimal suffering
2. It can be done by one person
3. It keeps the mess contained
4. It allows you to stand a little distance away from the bird, which can make the emotional aspect slightly easier

For this method, you’ll need:

• A killing cone (you can use a modified traffic cone)
• Sharp, strong tree loppers specifically kept for this purpose
• A bucket to catch blood

How to Humanely Cull a Chicken Using Tree Loppers

If you’ve decided culling is necessary, here’s the process I’ve found to be most humane:

1. Place the chicken head-first into the killing cone
2. Hold her by the feet as you lower her in
3. Once she’s fully in the cone, let go of her feet
4. The blood rushing to her head will cause her to relax
5. When she relaxes and her neck stretches out, position the tree loppers around her neck completely
6. Take a deep breath and squeeze the handles together in one smooth, continuous motion
7. Don’t stop until the handles are completely closed
8. Open the loppers and step away for a few minutes

The cone keeps the chicken contained during the involuntary muscle movements that happen after death, making the process less traumatic and messy.

Alternatives to Culling

If culling seems too difficult, there are some alternatives depending on your situation:

Rehoming

For non-productive or older birds that are otherwise healthy, finding them a new home can be a good option. Some people keep chickens as pets or are happy to take on older birds.

Medical Treatment

For sick or injured chickens, consulting with a poultry vet might reveal treatment options you weren’t aware of. Sometimes what seems untreatable actually has a solution.

Improving Living Conditions

Better nutrition, more space, and reduced stress can sometimes improve a chicken’s health and productivity, potentially avoiding the need for culling.

Innovative Approaches

For commercial operations, new technologies like in-ovo sex determination can identify the sex of embryos before hatching, potentially eliminating the need to cull day-old male chicks.

Is Culling Chickens Legal?

Culling chickens is legal in most places, though regulations about methods may vary. In some European countries like France and Germany, there have been steps taken to ban the culling of day-old male chicks, but in the United States, it remains standard practice in the egg industry.

Is Culling Chickens Cruel?

This is where things get subjective. When done properly using humane methods that cause minimal pain and distress, culling can be considered ethical, especially if the alternative is prolonged suffering. The most inhumane methods are those that cause extended suffering like drowning, freezing, or gassing with car exhaust.

My personal belief is that the most humane method is whichever is quickest and causes the least suffering, even if it’s harder for me to perform.

Is Culled Chicken Safe to Eat?

If the chicken was healthy and culled for reasons other than illness, the meat is generally safe to eat. However, if the bird was sick, especially with certain diseases, it’s best to discard the carcass rather than consume it. When in doubt, consult with a poultry veterinarian.

Final Thoughts

Culling a chicken is never an easy task, emotionally or physically. As someone who raises chickens, I believe it’s our responsibility to ensure our birds have a good quality of life and, when necessary, a humane end.

Culling is the selective removal of specific individuals from a population, or the rejection of unwanted items from a collection, to achieve goals like population control, genetic improvement, health management, or the selection of quality.

“Cull” and “kill” are similar but distinct terms; to kill is to cause death generally, while to cull is to selectively kill a portion of a population for a specific purpose, such as to control their numbers, eliminate undesirable traits, or improve the overall health of the group. Culling is a deliberate, systematic removal that serves a broader goal, whereas “kill” is a more general action.

Cull chickens when they are no longer productive layers, are unhealthy, injured, or no longer serve their purpose (e.g., meat birds, breeders). The best time to assess laying hens is in August or September after their peak laying season to identify poor producers.
