I have four welsh harlequin ducks that I got back at the end of april shipped from a farm (I had more but the raccoon attack...). Unfortunately for me, only one of the four is a female, which has also come down with this odd condition. It started with one of the drakes at about the time they were reaching adult size. I noticed him breathing very short quick breathes one day and so I isolated him. He still ate and drank just fine and there were no other symptoms (no mucus, coughing, sneezing), but he did seem to loose his voice and I'm not sure he has it back to the full extent. I researched online but could really not match up anything besides thinking maybe he ate something moldy and so I gave him charcoal in his food. After two days his breathing was back to normal and he seemed fine so I put him back with the flock (geese). About a month later (give or take) he began to do it again with the short quick breathing. My female duck also sadly began to do the same
. I did not isolate that time. After about two days they seemed back to normal. I have only noticed the female doing it one time, but the drake has went through this several times. It always goes away. What is going on here? Is this labored breathing a symptom of a disease or could it be parasites? Lice is a possibility. I am planning to treat the entire flock soon (chickens too). Has anyone experienced something similar?
I finally got around to editing and uploading some footage I took of the ducks breathing. This breathing lasts about two days and then returns to normal. My two other drakes have never shown signs (yet).
Ok, here are the videos:
