Ok, if she is that bad, you need to make her a chicken sling similar to the photo I posted earlier on page 1 I think. You can do that in your cage rather than a plastic box by tying the 4 corners of the piece of fabric (an old t shirt works well) to the bars of the cage you are using (you can secure them with the zip ties rather than knotting them) so that it makes like a trampoline and then cut a slit for each leg to go through and another hole where her vent is, for poop to drop through so she sits in it like a baby walker. That will keep her upright and you can then either zip tie the pots of food and water to the bars near to her head or cut a small gash in the fabric  in front of her and push the pots of food/water through the slash in the fabric so that she can reach. I will see if I can find some examples of what you are aiming for as a visual prompt.
