It looks like the red "stuff" is coming from the umbilical area. If that's the case, it didn't get a chance to close all the way, so now the chick is probably bleeding out. It sounds very terrible, but I have this problem a lot during hatching season. I am sorry.
The bleeding seems to have stopped now, however it's leg is still the wrong way. The she tries to move her leg just drags behind her, she tries to move it but it but it dosent do much good. Could it be dislocated? Also will the unbiblical area heal by itself?
