Hello, We have a 7 week old Blue Orpington pullet. She acts perfectly healthy, no discharges, swollen eyes, etc. She sneezes a "rattling" sneeze and shakes her head as she sneezes about every 5 or 10 mins. Started noticing a "light" sneeze about 4 days ago. It has since gotten louder with more of a "rattle" sound when she sneezes. Anyone have any suggestions? Should we separate and treat, or wait it out? Thank you in advance! Rand
