I am a new chick owner and I'm not sure if I'm being paranoid... I took 6 of my bigger, more feathered out chicks outside today (they are just over 2 weeks old). I was sitting outside in the little run with them and they were sneezing and I swear I felt liquid on my arm when they sneezed by me, like just a little speck...I brought them back inside and they seemed okay. They were only outside for 5 minutes or so since it started to get colder...everything else seems normal. Normal poops, eating, lively...is this normal?
