Thanks! I'm located in Pennsylvania. One bird in particular will let out a little sneeze when I put her down after holding her--very consistently. These aren't my first chickens, but this is a weird thing going on.
I have 4 new black sex link pullets who are 4 or 5 weeks old. I've noticed they are sneezing every couple of minutes. No discharge from eyes or beak. They're running around, cheeping, pecking, scratching, pooping, chasing bugs, flapping their wings, fluffing and preening their feathers, jumping...
