Hello - a couple of days ago my runner duck Eve looked like she was trying to pass an egg by flexing her butt, so I didn't think anything of it, I thought it was odd I saw her do it the next day too for a while. Then yesterday I noticed the flexing was in between her shoulder blades and she was opening and closing her mouth like she didn't feel well. I have tried: 1. feeling her abdomen to see if she has an egg in there - does not seem like it. She doesn't have a full abdomen either, and seems lighter than normal (however she is molting right now). 2. Putting her in a tub of warm water. She normally poops as soon as she gets in water and has not done so, so she may be backed up. 3. Tried to make her eat molasses in case she's constipated. She ate a little bit of the corn in molasses water but doesn't seem to like it. I'm going to try a turkey baster and stick in her mouth next (is that how you do it?) I took a short video of her in her condition so you can see the flexing she's doing - any suggestions would be much appreciated! I love her and want her to get better.
