My little 20 week old hen has constantly got a 'crusty' nose. I have wiped it (quite firmly) to remove the crust but then it starts running. I have noticed her sneezing a little too. Should I be concerned? I haven't noticed any of the others in the flock with these symptoms.
It's possible that she could have infectious bronchitis, but I would check to make sure that the coop ventilation is as good as it can be. Lack of ventilation, high temperatures in the coop, dusty conditions, and ammonia odor can cause respiratory symptoms. If it is respiratory bronchitis, symptoms are sneezing and nasal drainage that may last up to a month. There can be wrinkled egg shells and watery whites in the eggs.
