Hello everyone! I just got ducklings last Friday, and so far we have had a rough start. We have a stream in our backyard acre:/, so we decided to go let them play in ityesterday. We watched them the entire time, and they swam and sunbathed for about a half an hour. When it was time to come back in I noticed a couple of them sneezing. Is that normal? They weren't acting cold, is there any way they could have gotten like mud up their noses? Do I need to do something for them? Please help, I don't think that's normal!
