I have found two hens so far (one Monday the other one Tuesday night) that have the gurgling breathing sound, runny nose and watery eye. I have seperated them and each have received a dose of LA200 so far. I listened in the coop for a while last night and did not hear any more similar sounds. I occasionally have heard some sneezing(a few days before), but nothing I was alarmed about. I have had them all (except the two seperated) on Durmycin for about 4 days because of that sneezing I heard and because they are not willing to get out of the very cold rain. Any other ideas on what I could be doing or what I should not be doing? Any other meds to use?
