About a week and a half ago...or maybe two weeks... I had a Swedish duck (hen) loose almost all use of her left leg. We used to raise Rouen ducks and they had a tendency to get a leg out of joint, but they would always get better on their own. Well, after a few days, this duck had not gotten noticeably better and still a drake (sometimes even two, at a time) would mount her, which we knew must not be helping her leg any!! So, I isolated her in an extra pen we had. This evening, she was dead Almost the whole time she was isolated, it was very cold. We had one snowfall a couple of days ago, and another one today. These "Oklahoma" birds are not used to that kind of weather, so I thought that might have contributed to her death, by maybe partially-freezing her So what do you all think was wrong with her???
