I have a 8 week old chick that I noticed had some (possible) dried discharge on her nostril when I put her to bed tonight. I haven't noticed any additional symptoms of a respiratory issue but want to keep on top of this. Our outdoor temps have dropped down into the 40's recently. They had been out in the yard for 4 hours today and it was quite windy so I wasn't sure if that could cause the possible drainage. Is there something I can do to stop this before it gets to a point that I need antibiotics.
