Overview
A runny nose in a chicken can happen for a few different reasons, and it isn't always serious. Common causes include dust, damp housing, irritation from litter, or a mild respiratory infection. If it comes with other signs such as sneezing, watery eyes, swelling, breathing changes or a drop in appetite, it needs closer attention.
Things To Check
1. See whether the discharge is clear, cloudy, thick, or has a smell.
2. Check if one nostril or both nostrils are affected.
3. Look for sneezing, coughing, bubbling around the eyes, or noisy breathing.
4. Notice whether your chicken is eating, drinking and behaving normally.
5. Check the coop for dust, damp bedding, poor airflow or a strong ammonia smell.
6. Look for swelling around the face, eyes or wattles.
7. See whether any other birds in the flock have similar signs.
Common Causes
Dust, bedding irritation or poor coop ventilation are common reasons for a watery nose, especially if the problem is mild and there are no other signs.
A mild respiratory infection can also cause runny nostrils, sneezing and watery eyes. These signs may build up gradually or spread to other birds.
Less commonly, a blocked nostril, sinus irritation, or a more significant respiratory problem could be involved, particularly if the discharge is thick, persistent or one-sided.
What To Do
Start by keeping a close eye on your chicken and noting any changes in appetite, breathing or behaviour. Improve coop ventilation, replace damp or dusty bedding and keep the housing clean and dry.
It can also help to separate any bird that seems unwell from the rest of the flock, while still keeping it warm, calm and able to eat and drink easily. If the problem is still there after a short time, or other signs appear, speak to a vet who sees poultry.
Products That May Help
Good flock hygiene can be useful when you're managing a chicken with a runny nose, especially if you're cleaning housing, bedding and shared areas more often.
