New Pekin duck has down sticking to her bill frequently ,even had to pull feather out of a nostril.I don't see discharge,she looks healthy,has access to plenty water and can submerge head. I wonder if she is sick... I got her about a week ago from a big poultry farm- he has free ranging birds and at night shelters in huge barn...was pretty strongly ammonia scented but otherwise ,ok. Ungodly amounts of rain here,lately,too. Should I worry? The other duck is still fine...we got the new downy nose to replace our duck's partner who was killed by neighborhood dog. I did hear a chicken sneeze, tonight so starting to worry
