What Does It Mean When Chickens Vomit Water?

Understanding Why Chickens Vomit Water

Chicken owners often notice their birds vomiting up water. This can appear alarming, but is usually a harmless behavior. There are a few reasons why chickens vomit water.

Normal Regurgitation to Swallow Air

It is completely normal for chickens to occasionally regurgitate water or food. They do this purposefully to help swallow air into their crop. The crop is part of a chicken's digestive system used for storage.

Chickens don't have diaphragms or lips, so they cannot create suction to swallow air into their crops on their own. Instead, they use gravity and regurgitation to allow air intake. This air exposure helps break down food sitting in their crop.

Heat Stress Causing Heavy Panting

Another cause of chicken water vomiting is heat stress. Chickens cannot sweat like humans do to cool their bodies. Instead, chickens pant to alleviate heat through evaporative cooling.

This heavy panting can cause chickens to end up swallowing an excess of air. All this excess air in their system often gets expelled back out, along with water or crop contents their bodies are trying to make room for.

Providing Chickens With Shade and Cool Water

If you notice your flock vomiting water on hot summer days, take action to provide heat relief. Ensure chickens have a shaded area to get out of direct sunlight during the hottest hours.

Also make sure fresh, cool water is always available to chickens in the coop and run area. The water should be shaded as well so it doesn't get too warm in the sun. Chickens are less likely to guzzle down hot water which could lead to vomiting.

Overeating Causing Crop Impaction

On rare occasions, chickens will regurgitate water due to a crop impaction or blockage. This occurs if chickens eat too much coarse material without properly breaking it down first.

Long pieces of grass, litter, or other fibrous content can get lodged in a chicken's crop. The backed-up crop may then force contents back out the way they came in. Crop impactions can be life-threatening so require immediate veterinary attention.

Providing Proper Chicken Feed

A key way to avoid crop impaction is feeding an appropriate chicken diet. Adult chickens should eat a complete feed made for laying hens or adult flocks. This nutritionally formulated feed has the right composition for a chicken's crop to break down.

Chickens should also always have insoluble grit available to help grind up feed in their gizzards. And they should have unlimited access to fresh pellets and clean water. Restricting feed leading to gorging can cause crop problems.

Flock Ingesting Foreign or Spoiled Objects

Chickens are very attracted to brightly colored objects. They may gobble down foreign debris in the coop or run that gets lodged in their crop and vomited back up.

Spoiled feed or contaminated treats can also cause minor digestive upset. It's best not to leave piles of composting leaves or produce scraps chickens can access and potentially overeat.

Regular Coop and Run Cleaning

You can discourage chickens from pecking at and ingesting odd objects or debris by keeping their living space clean. Their coop and outdoor run area should be swept clear of poop, stale feed, and any garbage.

Use a deep layer of fresh, dry bedding in the coop. Pine shavings or rice hulls are safest options chickens won't be tempted to eat. The run should have dirt or sand substrate versus potentially ingestible grass or straw.

Toxic Items Causing Thirst and Regurgitation

In some cases, chicken vomiting water signals a poisoning. Chickens will desperately drink water trying to flush toxins ingested from their system. But this can cause more regurgitation as their body rebels against the poison.

Toxins chickens accidentally consume could come from lead paint, chemical cleaners, poisonous plants, or pesticides. Vomiting along with neurological signs warrants an emergency vet visit.

Protecting Chickens from Toxins

You can reduce the risk of chickens suffering poisoning by properly "chicken-proofing" your property. Scan for lead-based paint chips accessible to chickens. Only use pet and chicken-safe cleaners.

Identify and remove any poisonous plants. Only apply chemicals like pesticides when chickens are away from the area and make sure to follow reentry intervals.

When to Seek Emergency Care for Vomiting Chickens

In most cases, chickens regurgitating water or crop contents is totally normal. But if vomiting persists along with low energy, appetite loss or weight loss, respiratory issues, or neurological problems, promptly seek veterinary help.

A vet should also evaluate any chicken showing signs of dehydration from prolonged vomiting like sunken eyes, thick mucus in mouth, or skin tenting. They can provide emergency fluid therapy and crop massage to clear blockages.

With supportive care and removing access to toxins or foreign items, chickens can recover well from vomiting episodes. Only very rarely does regurgitation indicate an untreatable disease requiring humane euthanasia.
