Well I've been out there for the last 30 minutes taking care of it. I dipped it's beak in the water and then tipped it's head back (it's not even holding up it's head at this point). I did it about every 5 minutes for about 15 minutes. Then when I got up to walk away it suddenly seemed to have a surge of energy and almost got up on it's legs and started peeping really loud! Yay!!!! It stopped peeping and flopped down after only about 15 seconds, but I think that was a good sign. I dipped it's beak about 4 more times in the next 15 minutes. She had a second loud peeping spurt during that time too.
The umbilical cord/shell/membrane dried quite a bit and I tugged on it a little and it came off.
I'm totally hoping that tomorrow she has more strength. I want to put her back in with the momma, but I worry if she's not walking and not even peeping that she'll be shunned until the other ones are hatched and won't stay warm over night.
