ok well my chickens are 23 wks old and look and act healthy except that they are constantly sneezing and i dont know why i am not sure if it is from dust or if they are sick but they seem to do it all the time. their eyes are not watery and i havent noticed any nasal discharge. most of them seem to be dry but their poop changes. sometimes it is normal and sometimes it is a little yellow pile. idk so do yall think something is wrong or not? oh and one of the pullets makes a weird nose when it is panting during the heat of the day but only when it is panting please help. :|
