What could cause a chicken to sneeze or cough? One of my frizzle roos I noticed just today with this clear stuff in his mouth and he acted like he either was coughing or sneezing some. What are you ideas about this, should I separate him till I know waht's up? I don't really like doing that just cuz of the stress but if you think I should please share with me your ideas and suggestions. Sure would appreciate them!! Thankyou so much!
