She recently hatched( a month ago) and was perfectly fine. Running, hopping, etc. then suddenly she was broken. She cannot bear weight on her feet at all, I would love some advice, please
So she can’t stand up on her legs and her wing is splayed out? Or is she just putting it out to catch her fall?
As a starting point I would give scrambled egg with some human B multivitamin crushed up over it. Lack of the b vitamin riboflavin can cause issues with legs.
She is eating and drinking, but I have to hold her at just the right angle for her to drink, she can't get there on her own. I made her a little harness so that her feet would be under her, she can touch the ground, I haven't seen a whole lot of improvement, but she is hanging in there (literally)
Is your B complex a complete one, all the B's? I would keep at it, sometimes they can show improvement really quick, sometimes it takes longer. The B's are very safe, no worries of too much, extra will be excreted in droppings. You might consider adding a vitamin E capsule (400 iu) as well, give that for a week or two, see if it may help also. The E's can be overdosed, so that one can't be given as long as the B's. The sling is a good idea, it will help her stay upright, make it easier for her to eat and drink and poop normally.
