Well, I don't know if I'm just over worried after I read peoples stories here on respiratory diseases and other illnesses but.... My 2 pullets and 1 roo that are 7 weeks old occasionally sneeze now and again but nothing that seems serious...I'm not sure if they are gaping or gasping though.... OCCASIONALLY I see them look up a little and open their mouth. I thought this might be yawning, but as I read more I am afraid they are gaping...I mean I've seen them do this now and again for the past 2-3 weeks but everyone eats plenty acts normal and poops fine. Could this be respiratory disease or something else perhaps? I started putting some apple cider vinegar in their water and I think I notice less sneezing and "gaping"/"gasping" the past two days although I don't see them as much on the week days. There eyes look fine, and in the morning and during the day I don't see mucus build up or anything on their beaks so thats why I haven't been overly concerned... Should I consider getting some VetRX - Poultry Remedy and start them on it just to be careful?
