A chicken's crop is a part of its digestive system, located on its breast. It is a small pocket where food is stored before moving down to the stomach. The crop allows chickens to ingest food quickly and store it in a take-out container, breaking it down into smaller pieces when they reach a safe location. A normal crop feels swollen and slightly firm after a chicken eats, but it shrinks as the food is digested. However, if the crop remains swollen and hard, it could indicate an impacted crop, where food or fibrous material is stuck. This requires attention, as it could lead to malnutrition and dehydration. Other issues with the crop include sour crop, also known as thrush, a yeast infection caused by fungus, and pendulous crop, a less common issue.

The crop is a natural part of a chicken's digestive system
When a chicken picks up food with its beak, the tongue pushes it to the back of the mouth into its oesophagus, which empties into the crop. Food remains in the crop until it moves into the stomach (proventriculus). An empty crop stimulates a chicken's appetite, which is why they often eat so fast first thing in the morning. A full crop signals to the chicken to rest and stop eating, which is why hens often rest in the afternoon.
The crop is needed to fill the gaps in eating, such as overnight. It slowly contracts and pushes small amounts of food down through the tube toward the proventriculus or stomach, through the gizzard and on through the intestinal tract. The gizzard chews food by using small stones or grit to grind it up, as chickens do not have teeth.
Several abnormalities can occur in a chicken's crop, such as impacted, sour and pendulous crop. An impacted crop can be caused by a lack of grit or gravel to digest food, or by feeding long strands of grass or hay that are too fibrous. Sour crop, also known as thrush, is a fungal infection. Bad breath is generally the first sign of this. Pendulous crop is a less common problem in backyard chickens, and can be identified by a swollen crop.

The crop is located slightly to the right of a chicken's breastbone
The crop is a small, expandable muscle located slightly to the right of a chicken's breastbone, at the bottom of its neck. It is part of the chicken's digestive system, acting as a pocket to store food before it moves into the stomach. This allows chickens to ingest food quickly and store it in a safe location.
The crop is usually swollen and slightly firm after a chicken eats, but it shrinks as the food is digested. It is important to know what a normal crop feels like when it is full and when it is empty, so you can identify any problems. For example, if the crop feels squishy and the chicken's breath smells bad, this could be a sign of sour crop, a yeast infection caused by a fungus. Alternatively, if the crop feels hard and swollen and does not go down overnight, this could be a sign of impacted crop, where food or fibrous material is stuck in the crop.
If you suspect your chicken has a super big crop bone, it is important to monitor its weight, feed and water intake, and droppings. If the chicken is losing weight or becoming dehydrated, you should consult a veterinarian for advice.

A full crop is normal, but an overly large crop could be a sign of crop impaction
The crop is a muscular pouch located on the right side of a chicken's lower neck or upper breast area. It is a part of the digestive system, acting as a storage organ for food to be soaked and mixed before it moves down to the stomach. Food remains in the crop until it moves into the stomach, and it can hold a surprising amount of feed. An empty crop stimulates a chicken's appetite, which is why they often eat so fast first thing in the morning. A full crop signals to the chicken to rest and stop eating, which is why hens often rest in the afternoon.
If you suspect your chicken has an impacted crop, it is best to get her to a veterinarian. However, you can try to treat her at home, but be very careful as it is dangerous to force the contents of her crop up into her throat, as she could aspirate it and suffocate or get sick. One possible treatment is to take an eyedropper and fill it with edible oil like vegetable or olive oil. With assistance, drop the oil into the back of her mouth, allowing her to swallow it. Then, wait 15-20 minutes and gently massage the crop. The oil can help the mass pass.

Sour crop, a yeast infection, can be treated with Epsom salts and antifungal medication
The crop is a part of a chicken's digestive system, located on the right side of its lower neck or upper breast area. It is a small pouch where food is stored before moving further down the digestive tract. The crop allows chickens to ingest food quickly and store it in a "take-out container", breaking it down into smaller pieces later.
A chicken's crop normally feels swollen and slightly firm after the bird has eaten, but it shrinks as the food is digested. However, if the crop feels squishy and the chicken's breath smells bad or sour, it could indicate a yeast infection, also known as sour crop, thrush, or crop mycosis. This is a type of fungal infection.
Sour crop can be treated with a combination of Epsom salts and antifungal medication. Here is a step-by-step guide to treating sour crop:
- Clean and sanitize the feeders and drinkers used by the flock.
- Isolate the affected bird to prevent the spread of the infection.
- Flush the crop with an Epsom salt solution. Mix 1 teaspoon of Epsom salts in 1/2 cup of water, and carefully pour or squirt this solution down the bird's throat twice a day for 2-3 days. Ensure that the solution does not get into the bird's airway.
- Treat the underlying fungal infection. Copper sulfate is commonly used for this purpose, but it must be administered carefully to avoid overdosing, as it can be toxic. Prepare a solution by mixing 1/2 pound of copper sulfate (powdered bluestone) with 1/2 cup of vinegar, and dilute this in 1/2 gallon of water.
It is important to consult a veterinarian for guidance and support throughout the treatment process, especially during the flushing of the crop, as there is a risk of fluid entering the bird's airway.

Impacted crops can be treated at home but may require veterinary attention
The crop is a muscular pouch and part of a chicken's digestive system. It is located on the right side of the bird's lower neck or upper breast area, slightly below the beak, and serves as a small pocket to store food. An empty crop may not be palpable, but a full crop will feel swollen and slightly firm.
A chicken with an impacted crop may have a lump that does not change in size and feels hard. This can be caused by a lack of grit or gravel to aid digestion, or by consuming long strands of fibrous material such as grass or hay. Impacted crops can be treated at home, but it must be done carefully. One method is to use an eyedropper to administer a few drops of edible oil, such as vegetable or olive oil, into the back of the chicken's mouth. Allow the chicken to swallow the oil, wait 15-20 minutes, and then gently massage the crop. The oil can help the blockage pass. However, it is important to be extremely gentle during the massage, as forcing the contents of the crop up into the chicken's throat can cause aspiration, leading to suffocation or illness.
For more severe cases of impacted crop, or if home treatment is ineffective, veterinary attention is required. A veterinarian may recommend flushing the crop with water to loosen the impaction, but this should be done with caution to avoid forcing liquid into the bird's airway. In addition, it is important to never attempt to make a chicken with an impacted crop regurgitate, as this can be dangerous. Instead, monitor the chicken's weight, feed and water intake, and droppings. If the chicken becomes dehydrated and malnourished, end-of-life options may need to be considered.

Frequently asked questions
A chicken's crop is part of its digestive system, located on its breast. It is normal for a chicken's crop to be big and full at night, but it should be smaller in the morning. If the crop feels swollen and full after the chicken has eaten, this is normal.
Monitor the chicken's weight, feed and water intake, and droppings. If the chicken loses weight or its eyes become sunken, it may be dehydrated and malnourished. Remove access to food but allow the chicken to drink water and olive or vegetable oil. Massage the crop gently to encourage the contents to start moving.
If the crop feels squishy and the chicken has bad breath, this could be a sign of sour crop, also known as thrush, crop mycosis, or a yeast infection caused by a fungus.
Clean and sanitise the feeders and drinkers, isolate the chicken, and flush the crop with an Epsom salt solution. Then, treat the fungus with an antifungal medication or copper sulfate, being careful to avoid an overdose.
