I show chickens and these are show birds that are sick. They are coughing and sneezing. I can hear their breathing and it's raspy. They have fluid coming out of their noses and it crusts up into broogers. What comes out of their nose and sometimes cough it up it's a smelly smelly liquid. I have a show this weekend and one of the birds I'm supposed to take is like this. What do I do! I gave electrolytes to try to help them fight it
