2 week old meat birds, some are sneezing w/ no other symptoms. What is the best first step, I didn't raise them on medicated chick starter because I was trying to stay away from medication, maybe that was a bad plan?
A lot of times they sneeze due to the ammonia build up.... I would ventilate a little better get some kind of airflow in the brooder but not to the point where it creates a draft. Ventilation is tricky with chickens.... but a small problem and a simple management issue. If it gets worse it could be an actual disease.... most common would be MG aka Chronic Respiratory Disease *CRD*.
