Sour crop is quite common to cockatiel chicks, and is one of the main casuses of death to handfed cockatiel chicks. The crop isa a bird's food storage, it provides them with constant supply of energy for long flights. Sour crop is when the contents of the crop is not able to push through the digestive system and gets stuck in the crop. There may be many causes of sour crop; bacterial, yeast infection and impaction being the most common.
Impaction can be caused by irregular sized foods causing blockage in the crop. Handfed chicks rarely encounter this. It still occurs on at timeswhen the chicks ingested its nesting material. Breeders usually try the following:
- Feed a more diluted formula followed by a light crop massage
- Provide mineral oil in the food to loosen the contents and slowly massage the crop
- Saline solution to the bird and massage.
The following procedures must be done by your vet.
- Flushing the crop. A last resort, involves extracting the contents of the crop forcibly in to the mouth of the chick. Survival rate is not guaranteed, the smaller the chick, the riskier the attempt.
- Operation. cutting up the outer skin in to the crop, emptying it and sewing them back on. Depending on the size and age of the chick this should absolutely be done by your veterinarian.
Sour crop due to bacterial infection can be easily cured by administering antibiotics but can backfire to the chicks health, antibiotics kills all the bacteria in its apth, including the good ones, probiotics are applied after medication to replenish the good bacteria. Laboratory culture is used to determine sour crop due to bacterial infection. Fungi will not react on rash antibiotic treatment causing only the good bacteria to be eradicated. Unless in an emergency situation, antibiotics should be administered only by your veterinarian.
Fungus is the most common cause of sour crop in handfed chicks, the candida sp. strain is a fast growing fungus that developes a clay-like indigestible ball in the crop. It grows each feeding and your best and probably only option is to cure it through medication. feeding Nystatin ( brand name mycostatine)solution will immediately eliminate the clay ball.
Chicks fed by their parents have lesser risk of acquiring sour crop. Prevention is still the best cure.
