Hi everyone. I’m a newish chicken mama and I have a hen that I’m not sure exactly what to treat her for. She has sounded a little gurgly for a while (no swollen eyes, drainage, foamy eyes) ,but otherwise seemed healthy (eating and foraging with the rest of the flock. I treated her for 5 days with Denegard and finished that a couple days ago. She still sounded crackly/gurgly after treatment. But today when I let them out of the coop she stayed on the roost and was reluctant to come out. I picked her up and immediately noticed a foul smell with some thick, whitish fluid in her mouth. She sounded even more gurgly than normal and definitely doesn’t feel good. Not attempting to peck around, eat, or drink. I’m just not sure if I should be trying to treat her for sour crop or infectious coryza??
