I had to learn by doing it on my own after the first few times it's easy. I did wrap my Runner in a towel and held her between my knees. I'd def call the vet on Monday and let them know so they can give you what you need.. Will she drink? if so try making her recovery formula real soupy and see if she'll drink it?
I'll still try tomorrow though. She won't take any water really from me or if I'm around. She's also not inclined to drink if the other ducks aren't around, unless from her pool, they'd knock a dish over easily and probably end up drinking it on her.
