Help Please!! I have 3 Alive & Moving Malpositions!

[StephensonC]

Eggs #'s 20, 12 & 16. They are all on day 23. Most of the others hatched 2 days ago. These 3 pipped in the wrong place some time early this morning. I chipped away some shell, to establish and confirm their beaks. All 3 beaks are moving underneath the membrane. #'s 16 & 12 must have pecked a vein as there is a tiny bit of blood on the membrane, but neither are currently bleeding. #12 is the only one so far that has it's beak protruding from the membrane. I am currently researching how to/when to assist, but would love advice as to what to do. At this point, I am just waiting and giving it more time. But, if they are truly malpositioned, chances are they may not be able to get out. There again, I am currently waiting until that point. But at the same time, I want to be prepared for whatever may or may not. Thanks
