I have a 6 month old hen that has been sneezing and has a runny nose, she is eating and as active as usual. It has been extremely hot and humid lately, I did just change the pine shavings in the coop and she has been rolling in the dirt. No other chickens seem to be having any issues. When we got her she was already beak trimmed, I htought that maybe that could be part of the issue, she has to get so close to the food and ground to peck. Any thoughts or suggestions? Thanks!
