I've used human vitamins mixed with a little electrolytes on newly hatched chicks. A few drops with a syringe in the side of the beak. I have a hard time finding the right baby vitamins but I have tons of regular vitamins.I'll definitely try to get some pictures to share here when they start hatching.
Oh no poor little one! I haven't dealt with wry neck in such a young baby but I know they can get it even right after hatching. Does the nutridrench have vitemin E, selenium and B vitamins? I'd try giving her a few drops, but if it doesn't have all of those things I know poultry cell does have all those vitamins and is usually at tractor supply if you have one of those near you. I use human vitamins on my older babies who come down with wry neck since there little beaks are big enough I can use a syringe but I doubt that would work on such a young baby.
