That is good she didn't cough. It sounds like you did a good job with it. When some ducks have an injury or illness, the stress can stop them from laying. As long as she is eating and drinking well, that is a good sign.A picture or video would be great if you have a chance! If you don't mind me asking, what breeds do you have?
Thankfully, mine don't hiss at me, and I've only been bitten once (yesterday). Even my drakes are pretty calm, though they've started chasing my little rooster around the yard when both are free-ranging.
So far so good today, I think. I had a time getting her mouth open — yesterday, she was biting at everything, and today, she's keeping it clamped shut. I haven't really been able to get to the back of her throat, but it's such a tiny amount of liquid (I did 0.175). I got the syringe in and she bit down on it, so I squirted it out and she acted like she was drinking it (didn't cough or anything) and I never saw her spit anything out. I have a feeling we will end up at the vet next week, but I am hoping and praying it's not necessary. I just think it may need to be drained. The pocket of fluid seems a tiny bit smaller today, but it's still warm and pretty prominent. She doesn't seem as active as she was, and she hasn't laid an egg in about a week, but I think the daily chasing/soaking is probably stressing her out a bit. Plus, it's 90-something degrees here. Her appetite is good, she's not losing weight, and she can fight me with the best of them when I catch her.
I just hope I'm not drying her feet out with all of these daily Epsom salt soaks!
The Epsom salt soak may actually be helping dry out the fluid in the foot. If you are worried her feet are drying out, Vaseline can help keep moisture in her skin. Bag balm is another option too.
So this is my easiest girl to treat. She has been handled a lot and is pretty use to it now. I was Giving a pill and not a liquid medication. Hopefully that link works and shows how I restrain my ducks. With a syringe, I often put it on the ground, then grab it when I have the free hand.
I have a Pekin, a khaki Campbell, Saxony, swedish, Welsh harlequin, runners, Cayuga and Muscovy.
