I bought new chickens yesterday and noticed that 2 of them have runny noses and sneeze occasionally. I put those two in the garage last night just in case. Today I noticed a gross smell coming from their nasal drainage. They do not act sick. They eat and drink normally and run around like crazy. No swelling of the face and no eye drainage. The only problem seems to be the stinky snot. They also do not gurgle or open mouth breathe. What should I do with them?
