What is the white stuff in chicken feces?

It's impossible to give a definitive answer without seeing the chicken feces in question. However, there are a few possibilities for the white stuff you're observing:

1. Uric Acid: This is the main component of chicken waste and is a whitish, pasty substance. It's normal to see some uric acid mixed in with the feces.

2. Undigested Food: If the chicken is eating a lot of white food (like rice or bread), you might see small bits of this in the feces. This is also usually normal.

3. Parasites: Some intestinal parasites can leave white, worm-like deposits in chicken feces. If you see long, thin white strands, it's a good idea to consult a veterinarian.

4. Internal Issues: White, chalky, or cheesy deposits in the feces could indicate digestive problems like coccidiosis or internal parasites.

5. Medications: Some medications can cause white, chalky or powdery deposits in the feces.

To get an accurate answer, it's best to:

* Observe the consistency: Is it pasty, powdery, or stringy?

* Note the color: Is it white, yellow, or brown?

* Check for any other symptoms: Is the chicken acting lethargic, losing weight, or having diarrhea?

If you are concerned about the chicken's health, it's always best to consult a veterinarian. They can help you determine the cause of the white stuff and advise on the best course of action.
