Sour crop is a common health issue in chickens that can worry any backyard flock owner. If you’ve ever noticed your chicken acting sluggish, refusing food, or having a swollen crop, you might be dealing with sour crop. But don’t worry! This article will explain what sour crop is, why it happens, how to spot it, and what you can do to help your chickens recover. By the end, you’ll feel confident in managing this condition and keeping your flock healthy. Let’s dive in!
What Is Sour Crop?
Sour crop, also called candidiasis or thrush in chickens, is a condition where the crop—a small pouch in a chicken’s throat that stores food before digestion—gets infected or stops working properly. Normally, the crop empties food into the stomach overnight. However, when food stays in the crop too long, it can ferment, leading to a yeast infection caused by a fungus called Candida albicans. This makes the crop smell bad and can make your chicken sick.
Think of the crop like a temporary storage bag for food. When it’s working well, it’s like a smooth-running conveyor belt. But when it’s not, it’s like a bag of rotting fruit—yuck! Understanding sour crop is the first step to helping your chickens stay healthy.
Why Does Sour Crop Happen?
Sour crop happens when the crop doesn’t empty properly, allowing food to sit and ferment. Several things can cause this, such as:
- Eating the wrong things: Chickens love to peck at everything, but eating long grass, moldy food, or tough materials can clog the crop.
- Infections: Bacteria or fungi, like Candida albicans, can grow in the crop, especially after antibiotic use, which kills good bacteria.
- Stress: Changes in environment, new flock members, or extreme weather can upset a chicken’s digestion.
- Blockages: A blocked crop (called impacted crop) can lead to sour crop if not treated.
- Poor diet: Feeding too many treats or not enough grit (small stones chickens use to grind food) can cause problems.
For example, my neighbor Sarah once noticed her hen, Clucky, wasn’t eating. Clucky had been pecking at some moldy bread scraps Sarah accidentally left out. The mold caused a yeast overgrowth, leading to sour crop. Fortunately, Sarah caught it early and helped Clucky recover.
How to Spot Sour Crop in Your Chickens
Spotting sour crop early is key to helping your chicken feel better. Here are the signs to look for:
- Swollen crop: The crop feels full, squishy, or like a water balloon, even in the morning when it should be empty.
- Bad breath: If you gently press the crop and smell a sour, yeasty odor, that’s a big clue.
- Lethargy: Your chicken might seem tired, stand alone, or not move much.
- Loss of appetite: Chickens with sour crop often stop eating or drinking.
- Weight loss: If the condition lasts, your chicken may lose weight because it’s not digesting food properly.
- Vomiting: You might see your chicken shaking its head or spitting up smelly liquid.
If you notice these signs, act quickly. Sour crop can get worse if left untreated, and your chicken could become very sick.
Case Study: Bella the Hen
Let’s look at a real-life example. Jenny, a chicken keeper in Ohio, had a hen named Bella who started acting strange. Bella’s crop was huge, and she wasn’t eating her usual feed. Jenny checked Bella’s crop in the morning and found it still full. When she gently massaged it, a foul smell came out. Jenny suspected sour crop and called her local vet. The vet confirmed it was a yeast infection and suggested a simple treatment plan, which we’ll cover later. Within a week, Bella was back to her happy, clucking self!
How to Diagnose Sour Crop
If you think your chicken has sour crop, you can check at home before calling a vet. Here’s how:
- Feel the crop: Gently press the crop (located at the base of the neck). A healthy crop feels soft and empty in the morning. A sour crop feels full and squishy.
- Smell the breath: Carefully press the crop and smell for a sour or yeasty odor.
- Check behavior: Watch for signs like lethargy, not eating, or vomiting.
If you’re unsure, take your chicken to a vet. They can confirm sour crop with a quick exam and might test for yeast or bacteria. According to The Chicken Chick, checking the crop in the morning is the easiest way to spot problems.

How to Treat Sour Crop
Treating sour crop can be simple if you catch it early. Here’s a step-by-step guide to help your chicken recover:
Step 1: Isolate the Chicken
Move the sick chicken to a quiet, clean area away from the flock. This reduces stress and prevents other chickens from pecking at it. Plus, it makes it easier to monitor.
Step 2: Empty the Crop
To help the crop empty, try these tips:
- Withhold food: Don’t feed the chicken for 12-24 hours, but provide fresh water. This gives the crop time to clear out.
- Massage the crop: Gently massage the crop upward to encourage emptying. Be careful not to push too hard, as this can hurt the chicken.
- Encourage vomiting: If the vet approves, you can hold the chicken upside down (briefly!) to help it expel crop contents. Only do this with guidance.
Step 3: Flush the Crop
Flushing the crop removes bad bacteria and yeast. You can use:
- Apple cider vinegar: Mix 1 teaspoon of raw, unfiltered apple cider vinegar (like Bragg’s) in 1 liter of water. Offer this as the chicken’s only water for a day.
- Epsom salt solution: Mix 1 teaspoon of Epsom salt in 1 cup of warm water. Use a syringe (without a needle) to slowly give 10-15 ml to the chicken, as advised by Backyard Chickens.
Step 4: Restore Good Bacteria
After flushing, give your chicken probiotics to rebuild healthy gut bacteria. You can find poultry probiotics at feed stores or mix a small amount of plain, unsweetened yogurt into their feed.
Step 5: Monitor and Feed Carefully
Once the crop feels normal, slowly reintroduce food. Start with soft, easy-to-digest feed like scrambled eggs or moistened chicken feed. Avoid treats or tough foods for a few days.
When to Call a Vet
If the crop doesn’t improve in 48 hours, or if your chicken gets worse, call a vet. They might prescribe antifungal medication like Nystatin to treat the yeast infection.
Preventing Sour Crop in Your Flock
Preventing sour crop is easier than treating it. Here are some simple tips to keep your chickens healthy:
- Feed a balanced diet: Stick to high-quality chicken feed and limit treats like bread or pasta. According to Purina Mills, a good diet prevents digestive issues.
- Provide grit: Chickens need grit to grind food in their gizzard. Offer free-choice grit in a separate container.
- Keep the coop clean: Remove moldy food or wet bedding to avoid infections.
- Check crops regularly: Feel your chickens’ crops every few weeks to catch problems early.
- Reduce stress: Avoid sudden changes in the flock, like adding new chickens, and provide shade and water during hot weather.
For instance, my friend Tom started checking his flock’s crops every Sunday after one of his hens got sour crop. This simple habit helped him catch issues early and keep his chickens healthy.
FAQs About Sour Crop
Q: Can it go away on its own?
