I'm a little panicked. We went though a chicken disease issue last fall and had to cull and start over, and runny noses were the first symptom. (Everything has since been disinfected and all new chickens are 100% healthy.) My ducklings came from TSC a few days ago. They've been under a heat lamp most of the time except when they are out marching around with us for about 15 minutes at a time, or taking a daily swim in some warm water in the tub. They all act healthy other than clear runny noses. What should I do? I read that ducks don't get diseases as easily as chickens, and I have no idea where they would have gotten a disease anyway unless they got it at TSC before I brought them home...they didn't have runny noses this morning! Help!
