I have a 14 weekish BLR Wyandotte pullet that is sneezing and she seems to have a gurgling sound when she breathes. I have never seen this, and no one else in the flock is sick. My little pullet seems to want to sleep a lot. I have put Sav-A-Chick in the water to help her, but since I don't know what is wrong, I don't know what else to do.
Any advice ?
