The crop is a sac-like organ and the first stage of digestion for a chicken, where food is stored after being swallowed. In healthy chickens, the crop should be empty in the morning and will increase in size as the chicken eats throughout the day. If the crop does not empty, it may be impacted or the chicken may have a sour crop. An impacted crop is caused by a blockage in the crop, which can be caused by foreign objects such as grass, plastic, or string. A sour crop occurs when there is an imbalance in the crop's natural pH levels, allowing harmful fungi to thrive and causing fermentation. Treatment for an impacted crop includes massaging the crop to break down the blockage, and providing the chicken with water but no food. If the blockage is severe, a veterinarian may need to perform a procedure to cut the crop open and empty it. Treatment for a sour crop is similar, including isolating the chicken and providing water but no food for 24 hours. If there is no improvement after a few days, a vet may need to flush or empty the crop and treat the chicken with anti-fungal medication.

Identify the problem: Check for symptoms like reduced appetite, weight loss, and depression
To identify if your chicken is facing crop issues, it is important to be vigilant about symptoms and conduct regular crop checks. A chicken's crop is located on the middle right side of their breast. It is a small muscle pouch that acts as a "holding tank" for food until it can be digested. When functioning properly, the crop will be very full and distended at the end of the day, and empty and flat the next morning.
To check for crop issues, first ensure that your chicken has eaten recently, as you will have more success in locating the crop when it is full of food. Pick up your chicken with its tail towards you and its beak facing away. Gently feel the center right side of its breast. The crop will feel like a firm or doughy ball. If the crop feels squishy and full, and the chicken's breath smells sour, it could indicate a sour crop, which is caused by a pH change and fermentation in the crop.
If the crop is not emptying properly, your chicken may experience reduced appetite, lethargy, and weight loss. To diagnose a crop problem, you can test if the crop is emptying overnight by removing your chicken's food and water after they have roosted in the evening. In the morning, check the crop. If it is small, firm, and hard to distinguish, then it has emptied properly. If the crop is still full, it is likely impacted.
In addition to reduced appetite and weight loss, other symptoms of crop impaction include lethargy and laboured breathing if the impaction presses against the windpipe. Weight loss in chickens can also be caused by stress, intestinal worms and parasites, illness, environmental changes, and overcrowding. Broody hens that stay in their nesting boxes and eat very little can also experience weight loss. Therefore, it is important to provide access to food and gently encourage movement.

Home remedies: Try massaging the crop, giving water, and withholding food for 24 hours
If your chicken has a crop issue, it is important to first determine whether it is impacted crop or sour crop. Impacted crop occurs when the crop is blocked by something the chicken has ingested, such as long grass, straw, or foreign objects. The crop will feel hard and firm to the touch. Sour crop, on the other hand, is caused by an overgrowth of yeast, particularly Candida albicans, which leads to fermentation of food inside the crop. It is identified by a full, squishy crop and sour-smelling breath.
If your chicken is displaying symptoms of impacted crop, the first step is to withhold food for 12 to 24 hours. During this time, ensure your chicken has access to plenty of fresh, clean water. The water will help get matter moving through the crop. You can also give your chicken a calming, cooled herbal tea in place of water to help it relax while it is isolated.
If your chicken is displaying symptoms of sour crop, it is important to provide it with plenty of fresh water to help the crop recover from the blockage, flush out any fungus, and restore good crop bacteria. You can also add apple cider vinegar to the water to help balance the pH levels in the crop and combat the yeast infection.
In both cases of impacted crop and sour crop, massaging the crop is a valuable technique. Gently massage the crop from top to bottom (throat to breast) to help break down the blockage and encourage movement. You should massage the crop several times a day for 45 seconds to 3 minutes each time. If your chicken has impacted crop, you can also administer a small amount of oil to help break up the blockage.
If, after 24 hours, the crop still refuses to empty, you may need to consult a veterinarian for further treatment options.

Medical treatments: For severe cases, a vet may flush the crop or perform surgery
Impacted crop is a common emergency that all chicken keepers should be able to identify and treat early. The crop is a small muscle pouch located on the right side of the breast, in the centre below the neck. It acts as a holding tank for food until it can be digested in the stomach and gizzard. A chicken's crop will be very full and distended at the end of the day and will be completely empty and flat the next morning. If the crop is still full in the morning, the chicken likely has an impacted crop. This can be caused by eating long grass, which binds with feed, or by eating foreign objects such as sticks.
If a chicken has an impacted crop, it may be necessary for a vet to perform surgery to remove the material from the crop. This is often a simple procedure that can be carried out while the chicken is conscious, but it may require general anaesthesia in some cases. It is very easy to injure or kill a chicken attempting this procedure at home, so it should only be done by a licensed vet.
Before resorting to surgery, there are some home remedies that can be attempted to clear the obstruction. These include massaging the crop to try to break down the blockage, and giving the chicken water but withholding food until the crop is at least half empty. In some cases, it may be recommended to give the chicken a mixture of water and baking soda using a syringe, but this method carries a risk of drowning the chicken. Other treatments include olive oil or vegetable oil, miconazole vaginal cream, Metamucil, and papaya enzyme.

Prevention: Avoid access to long grass, string, plastic, or straw to prevent blockages
To prevent blockages in a chicken's crop, it is important to avoid giving them access to long grass, string, plastic, or straw. These items can cause blockages in the crop, which is a potentially serious condition that may require veterinary treatment.
The crop is an enlarged part of the oesophagus, located at the base of the neck, and is the first stage of digestion for a chicken. It is where food is stored after being swallowed, allowing chickens to eat a lot at once and then digest their food slowly while they preen, bathe, or sleep. Under normal circumstances, the crop will empty in 2-4 hours. However, in birds with crop impaction, the crop will not empty, and the contents will feel firm.
Impacted crop is caused by a blockage in the crop, which can be the result of consuming long grass, tough stems of woody grass, or other foreign objects such as bailing twine, metal, plastic, or string. These items can get tangled in the crop and obstruct the normal emptying process. To prevent blockages, it is crucial to keep chickens away from these potential hazards.
By denying chickens access to long grass, string, plastic, and straw, you can reduce the risk of crop blockages and help maintain their digestive health. This preventive measure is an important aspect of responsible chicken care and can save you from having to deal with the more complex treatments that may be required for impacted crops.
If you suspect your chicken may have a blockage or impacted crop, it is important to monitor their droppings, quantity, and texture. Additionally, you can perform a crop-fullness test by quarantining the chicken and removing its food and water source in the evening. In the morning, feel the crop to assess its fullness. If the crop still feels full, squishy, and soft, or if the chicken has sour-smelling breath, it may be suffering from sour crop, which is a consequence of GI stasis or crop impaction. In such cases, it is recommended to consult a veterinarian for proper diagnosis and treatment.

Feeding practices: Encourage gradual feeding and limit access to dry poultry feed to prevent overfilling
The crop is an enlarged part of the oesophagus, located at the base of the neck, to the right of the trachea at the thoracic inlet. It is the first stage of digestion for a chicken, storing feed while the proventriculus and gizzard are full. The crop should empty in 2-4 hours, and in a healthy chicken, it will be empty first thing in the morning.
To prevent crop impaction, encourage gradual feeding and limit access to dry poultry feed. This is because birds that have been off feed for a long time may overeat and overfill their crops with dry poultry feed. This feed can increase in volume when the birds drink water, adding pressure to the oesophagus and blocking the normal transit of feed.
If a chicken has an impacted crop, it will feel full and a little like dough, and will not clear. A chicken with an impacted crop may show reduced appetite, weight loss, and depression. An impacted crop can be caused by eating long grass, which binds with feed, or by consuming foreign objects such as plastic or string, which can obstruct the normal emptying process.
If you suspect your chicken has an impacted crop, you can try massaging the crop to break down the blockage. First, withhold food and water for 24 hours, then massage the crop several times a day, from the top to the bottom (throat to breast). Adding warm water to the crop before massaging can help to hydrate and soften the contents. If massaging the crop does not help, you may need to consult a vet.

An empty crop will feel small, flat, and hard. A full crop will be easy to feel and will be squishy and soft. A fully impacted crop will feel large and hard.
Sour crop is a consequence of GI stasis or crop impaction. As material sits in the crop, it starts to ferment and gets yeast growth. This leads to fermentation of the food in the crop, causing it to sour.
Isolate the chicken and provide ample water. Do not provide food or water for the first 24 hours. Massage the crop several times a day to try to break up any blockages.
Impacted crop is caused by a blockage in the crop. This can be caused by tough stems of woody grass or other things that get stuck, such as bailing twine, that cannot pass from the crop down into the proventriculus.
