Overview
Crusty nostrils in a chicken are often caused by dried mucus, dust, or a mild irritation, but they can also be a sign of a respiratory problem. If your bird otherwise seems bright and is eating normally, it may be something minor, but it’s still worth checking closely.
Things To Check
1. Check whether both nostrils are affected or just one, as one-sided crusting can sometimes point to a local blockage or injury.
2. Look for any discharge, swelling, sneezing, bubbling, or a wet sound when the bird breathes.
3. Notice whether the eyes are clear or whether there is facial swelling, tearfulness, or puffiness around the head.
4. Check if the crust looks like dry dirt, feed dust, mud, or a thicker sticky discharge.
5. Watch the chicken’s breathing at rest to see if it is open-mouthed, noisy, or more effortful than usual.
6. Consider whether the coop is dusty, poorly ventilated, damp, or has bedding that seems to irritate the birds.
7. See whether any other birds in the flock have similar signs, which may suggest an environmental or contagious issue.
Common Causes
The most common cause is simple drying of mucus or dust around the nostrils, especially in dry, dusty, or dirty housing.
Another common reason is mild irritation from bedding, feed dust, or poor airflow in the coop.
Crusty nostrils can also happen with a mild upper respiratory infection, particularly if there is sneezing, discharge, or reduced energy as well.
Less commonly, a blocked nostril, a foreign body, or a more significant respiratory illness may be involved.
What To Do
Start by keeping an eye on the bird for any change in breathing, appetite, activity, or the look of the discharge.
Improve coop airflow, reduce dust where you can, and make sure bedding is clean and not irritating the birds.
If the crust is soft and only on the outside, you can gently soften it with a little warm damp cotton wool and avoid picking at it.
Check the rest of the flock too, because a pattern across several birds is more suggestive of an environmental or infectious issue.
If the crusting comes back, worsens, or is joined by sneezing, facial swelling, or breathing changes, it’s sensible to seek veterinary advice.
Products That May Help
