I'm nowhere near Florida, but I can help with the eating/drinking issue. If you lay a drop of liquid alongside a bird's closed beak, they swallow automatically. If you need to get water, electrolytes or food into your hen, take advantage of that reflex. You'll need to turn your feed into "soup." Egg yolk or super runny scrambled eggs should work, but If the stuff won't go into and out of an eyedropper, it's not runny enough. It has to be able to flow into her mouth and slide down her throat. Lay the liquid alongside her closed beak like you would a drop of water. It doesn't always work, but I've been pretty lucky with the method, so far.
Keep us posted. You have a lot of people rooting for you!
