Update on my late bloomer - no progress overnight so I decided to investigate before turning off the incubator. I heard chirping immediately when I opened it and figured I should at least see if it's just trapped in there. It definitely was, she looks formed properly and all but as I was peeling away the shell and membrane, I caused a little bit of bleeding. I stopped right away as I had already done quite a bit. I could also see that her belly is sort of transparent looking and I am positive she didn't finish absorbing the yolk (clearly some is in there as it's big and round). She is pretty weak and one of her legs is tucked up from being stuck for so long. I put her back in the incubator and she immediately busted the rest of the way out of the shell. Time will tell, I don't have high hopes but at least I did what I felt was right and I'm prepared to cull if I have to at this point.
