Flock immunity and gut health

When it comes to chicken health, understanding flock immunity and gut health is essential for raising resilient backyard birds. Just like us, chickens benefit from a healthy digestive system and strong immune function. And, like humans, the two are connected. Whether you’re a seasoned flock raiser or looking to level up your chicken care, we’ll walk you through how to keep your hens healthy naturally by improving their gut health, immunity, and overall well-being.

Supporting a resilient flock

Learning the key factors that contribute to optimal chicken health is the foundation for overall flock fortitude. Chicken keepers have the ability to influence their hens’ health in a number of ways, starting with understanding what flock immunity really means, and how to encourage it naturally.

What is flock immunity?

Flock immunity refers to your chickens’ collective ability to resist and recover from disease. It isn’t about a single hen’s strength, it’s about the overall robustness of the group. Each chicken’s immune system contributes to the vitality of the whole flock. A stressed or undernourished hen can become a weak link, making the entire group more vulnerable to illness.

Here are key points to understand about flock immunity:

It’s dependent upon the health of each individual chicken.
Stress, poor nutrition, overcrowding, or parasites can suppress immunity.
Creating an environment that supports strong birds benefits the entire flock.

Housing your flock in an easy-to-clean, predator-resistent coop – like our line of Eglu Chicken Coops – is the first and most important step toward boosting flock immunity. Your chicken coop should be thoroughly cleaned on a regular basis, and built from materials that prevent parasites from taking up residence and insulated against the elements. Giving your hens a supportive home is one of the simplest ways to give them a leg up for the rest of their lives.

The role of gut health in your hens

Did you know that 70-80% of a chicken’s immune system function is housed in its digestive tract? That’s why chicken gut health is so crucial. A balanced microbiome supports:

Nutrient absorption
Resistance to pathogens
Regulation of inflammation
Overall energy and growth

Poor gut health can lead to lethargy, poor feather condition, messy droppings, and increased susceptibility to parasites and illness.

How to support good gut health

Improving chicken gut health starts with their daily care. Here’s how to keep your chickens healthy naturally.

High-quality diet

Feed a nutritionally complete layer feed consisting of 16-18% protein to support their energy requirements. Supplement with fresh greens and grass and scratch grains (in moderation). Chicken-friendly herbs like oregano can also be offered in with their feed for a nutritional boost. Fermenting your flock’s feed can also boost its probiotic content to help balance their gut biome.

Clean water

Fresh, clean water available at all times is vital to your hens’ health. Mix in electrolytes during the hot summer months to give them extra support, and add apple cider vinegar to their water during their annual chicken molt in the fall to promote healthy feather regrowth.

Grit and forage

Allowing chickens to free-range when possible will help them both physically and mentally. Chickens are natural foragers and will find what their bodies are craving to balance their digestion. Use chicken fencing to create safe foraging spaces, or a mobile chicken coop to give them access to fresh offerings. Free-ranging hens will ingest the grit they need for digestion, but supplemental grit should be supplied to chicks or adult chickens that don’t have access to dirt.

Treats and enrichment

Playing with your food is encouraged when you’re a chicken. A Caddi Chicken Treat Holder stocked with fresh greens encourages foraging behaviors while rewarding them with an immune system-supporting snack. Place scratch grains in a peck toy to reduce waste and to put your chickens’ critical thinking skills to good use.

Protecting your flock from illness

Preventative care plays a big role in flock immunity. These basic steps will help boost your birds’ natural ability to fend off illness, and help maintain a supportive environment:

Clean your chicken coop regularly to prevent bacteria from building up.
Quarantine any new flock members before introductions are made.
Avoid overcrowding, which causes stress and increases the spread of illness.
Limit exposure to wild birds by using waterproof chicken run covers and securing feed.

Give your hens a chicken health check on a routine basis to help you spot and head off any potential problems.

What to do when flock immunity is compromised

Even under the best conditions, sometimes issues can arise. Common times for your flock’s immunity to be put to the test are during their annual molt, when new flock members are introduced, during extreme weather, or if parasites are present. Be on the lookout for these signs of illness or stress within your flock:

Diarrhea or repeat occurrences of unusual droppings
Loss of appetite or poor body condition score
Lethargy or isolating behavior
Feather pecking or visible irritation
Decrease in egg production or odd-shaped eggs
Avoiding roosting areas, especially in wooden chicken coops

If you suspect illness, isolate the affected bird in a clean space away from the rest of the flock. Support with electrolytes and probiotics, and contact your veterinarian for next steps.

Omlet and your flock
