I have 8 Bantam chicks that are 13 days old. I work from home so I try and rotate through the chicks periodically each day, holding them in my hand or my lap as I work at my desk. Today I did my usual holding rotation and noticed one Silkie that was on my lap kept sneezing. I THINK it was sneezing at least. Opens his beak for a second and a little jump and sound, seems like a sneeze. Should I be worried? Can they just get dusty and sneeze like us, or is it definitely something to be concerned about? He did seem a little more dusty than the others for some reason. If this is bad, what should I do next?
