need help figuring out whats wrong and what to do.... one of my sons Japanese pullets (4mo. old) is weezing, she is making a sound as if you where squeezing a squeek toy slowly, and then occasionally sneezing. She is the only one with the symptoms. Her housing is off the ground wire bottom coop. It's a cage for show prep but the younger chicks are in there until they are big enough to go in with the other bantams. She is on chick grower/finisher and access to fresh water. The temps here in Central Texas are reaching 104 degrees so she definitely didn't get cold. Do I need to separate her and any suggestions on what could be wrong?
