NEED HELP ASAP! Duckling has seizures, nutritional issue?

[Frodo the Pekin]

My 3-4 week old duckling has been having these seizures a couple of timed per day and I'm so afraid she might die from it. What she does is she suddenly starts shaking her neck, falling down and throwing her neck on her back. One such seizures from today is on the video linked below. I am thinking it is a thiamine or vit E deficiency and I have this vitamin complex called SeleVit Sol that I used to get for niacin deficiency. Below are the listed ingredients. The pharmacist said 1mL/2L of water and so did the internet when I looked for that complex online. But it feels too little and I am afraid that not giving her enough asap will end up having the seizures killing her. Please advise! Thank you.

PS: I'll be going on vacation 4 days from now and what scares me the most is that she won't get the proper care from the friend coming over to feed and give my animals their water. I need to get her at least a bit better before then

What are you feeding it?

What are you feeding it?

It's a mill mix from stuff my family grows. Corn, grain, sunflower seeds and soy. I add one tbsp of brewers yeast per cup of feed. I also mix in water with a small amount (so as to not overdose with any of the vitamins since I already add it to the drinking water) of the vitamin complex I was talking about.

She's just had a couple more seizures in a very short time. The last of which she had right about now and it seemed so much worse. I'm so afraid for her. Should I take her in my room and separate her from the rest? They tend to be quite messy and since she sits so much she always gets all wet and nasty.. I just really don't want to lose her, it hurts to see her like this especially since she used to be the most active of all her 4 siblings just a week back...

I really hope your little duckling makes it!

Thank you!!! I made the decision to move her in with me.. this way I can supplement more vitamins without harming the rest of the ducklings, and I can keep her from hurting herself during seizures. I just hope she'll improve before I leave
