I have 10 ducks and 2 geese I ordered from Metzer Farms on 3/22/10. When they were about three weeks old I noticed one of the White Crested Ducks had a cloudy, watery eye, and was having trouble seeing out of it. I assumed she had hurt herself somehow, and I didn't really worry about it much until they recently began going to the pond during the day. She always gets left behind when we heard them up and down the hill, so I usually carry her. Today, after we brought them up from the from the pond I noticed the White Crested duck shaking her head, like she was choking. I opened her mouth and felt her throat, but I didn't find a foxtail or a fishhook (this has happened to different ducks in the past). I tried to get her to drink, but she couldn't seem to control her head. I set her down, and she would fall over and run into the fence, so I put her in the pool. She turned over sideways and began sinking, so I held her in the water until she could finally control herself. When I set her on the ground near her flock mates She was still shaking slightly. This all lasted about 2 or 3 minutes before she could walk again. Did she have a seizure or something? I am really concerned about her now, she is always left behind and now she starts flopping around uncontrollably. None of the other ducks and geese have any issues, and they all eat the same food. What could be wrong with her, and is there any way to treat it? Thank you for any suggestions!
