She survived the night. She fell off her box once and i put her up on it right away. I am sleeping on a mattress on the floor next to her so i can hear it if she falls, but it is only 8' high and there is carpet so she will not get hurt. She ate a little water soaked bread this morning and about 20 sunflower kernels.
My last chicken died the same way and they really hate it when you open their beaks to give them water so i feel if they have the strength to stand, they can drink water if offered to them up close so they don't have to stoop down. At least it is not hot so they need a lot of water right now and she obviously is no longer laying eggs which requires a lot more water.
take an eye dropper and rub it lightly back and forth from tip to corner of her beak, the water will go in her mouth and she will swallow. I am nursing a silkie back to health after my rabbit attacked her and tore a 1 inch chunk out of her rump, severed her wing where it meets the body and nearly slit her throat. she is now refusing to eat too, but I've found that canned mixed veggies are her new favorite, they are soft and easy to eat. good luck!
