All my ducks but the youngest hen started acting so strangely. They all started doing the bobbing, and making the come hither noises, but they also got puffy. I mean real puffy, so puffy I could see their oil glands. Is that usual? And then they would drink from the water buckets and it was like they were tipping over forwards and they would land on their chests and sit, till the next drink. All of them, all puffy like, tipping forward after a drink. Finally my new silky drake, Mario, mounted a female. But now he won't stop panting. I watched him for a good 20 minutes afterwards... let me go check... okay he's stopped now, but it was worrying the heck outa me. So is that all normal behavior? It was certainly awesome to watch all the activity going on, but this newb here has never seen anything like it.
