I agree it did wonders for my Runner once I started tube-feeding her. It took 5 days of tube feeding before she started eating on her own so don't get discouraged if she doesn't start to eat right away. Hopefully, it won't take 5 days for your duck.
That's awesome, Just be careful and not give her too much that she aspirates on it, meaning it comes back up. Practice makes perfect as the old saying goes.
How is she doing?
First time I tube fed I was a nervous wreck but after that confidence builds and it works fine. Keep us updated you’re doing great caring for her. Love hearing doing good!
Wrap her in a towel like a burrito and sit her between your legs so you have better control it helps to someone help the first few times till you get the hang of it
Have you tried making her pellets into a soup? put warm water on them and see if she'll drink it with you holding the bowl up so she doesn't have to bend her neck.
Okay here is another way that is safer than squirting into the mouh where it could go down the wrong way...
