So... we helped it, DH just cracked the shell a little so the two halves could completely come apart, then he gently pulled the top half off. Started peeping and stretching out right away, then just laid there for a while. We mixed up some of that Sav-A-Chick electrolyte stuff for her (and #3 since she was not nearly as vigorous as the first two chicks, doing great now), and gave a few drops with an eye-dropper then put her back in the incubator. She was still attached to the bottom half of the shell (via the umbilical cord?), so we were really gentle and moved her and the shell together. After she was in the incubator a while longer she started peeping and chirping more and trying to stand up. She eventually came unattached from her shell as she was dragging it around the incubator trying to walk. She seems to be doing much better now, I'm glad we intervened because she really seemed like she was giving up for a while there.
In other news, when I reached in to help with #4, I noticed another egg that had some fluid that leaked out from the pointy end... like maybe it tried to pip at the wrong end? The fluid had mostly dried by the time I saw it (was pointed towards the wall of the incubator). Is it a goner?
Haven't had any pips that I can see/hear from the other 7 eggs

There's still time right? Today was day 21, but it's possible that some will pip and hatch late, right?
