Okay, so I don't know if this duck was doing this intentionally (it had never occurred to me that this could be intentional) but here is a pic: https://www.backyardchickens.com/forum/uploads/23298_upside_down_duck.jpg he seemed to have a little trouble righting himself from this position... I looked for other posts regarding this situation - someone else posted a pic above. So I see others have it happen, by any idea why? My duck books give no explanation but I was sick to death the following 24 hours worrying about him. He's not even a year old. I'm wondering if he's too fat? Other people said it could be heat - but it's cold out. So the story: I found him the other night like this when I came home from shopping. It's 40's/50's out and dark at 430pm. I thought he had gotten attacked. I lock all my chickens/ducks up at night, but sometimes don't do it as early as dinner. He could NOT flip over. My Old English Sheepdog that he bites all the time (the duck bites the dog) went right up to him, sniffing away. Nothing --- he just laid there flapping his feet. Then I helped him, he was obsessed with how dirty he was, so he drank, bathed and ate. He appeared dizzy and clumsy at first. I had to wonder how long he'd been laying there. He's fine now - no signs of injury whatsoever, and he doesn't feel that fat. Anyone else have this problem?
