Thanks everyone for all the great advice.
Crop, feathers and eyes look normal. She seems better today, but still a bit of a problem with balance, although it's not as bad as it was. She gobbled down the good food (oatmeal and basmati rice) She just pooped on my desk so I got a good look at it, watery with some white and in the middle of the spot, something that looked yellowy-brown, almost the color of cooked egg yolk but a little darker. I've been keeping her in a plastic bin in the bathroom, but she much prefers to "roost' on the side of the bin.
I got the vitamins, but she didn't really eat last night, she may have been full with of oatmeal, I felt her crop, it was pretty hard.
She was born to a wild hen, but I removed her from her mother just prior to hatching becuase we were having a problem with fire ants getting into the eggs when the chick first pecked a hole. Her mother is fine, as are her siblings. I have the mother in a pen since we have a lot of predators and the wild chicks rarely survive if left alone. Mom occupies the pen next to the one this chick was in.
I'll order the AviaCharge 2000 if I can't get it at the feed store today. Also working on getting a picture of her to post.
Thanks again, will keep you posted!
