Update-
Just checked the incubator before I went to bed to find she has pushed herself out, I had actually taken some more shell away but left both membranes still attached, basically took the air cell lid off...some how in the five hour she had flip herself over so her bum was at the air sac and not her beak, if literally lost her beak in there, I couldn't see any yolk through the membrane but she still had blood vessels to absorb so I just letter ee with her bottom half of the shell, well she's got herself out anyway well both her legs there was the shell still attached to her back, was very sticky indeed, and I can see she has a weird toe, it's bent so will wait and check it out tomorrow. But yeah she's hatched! A miricle! Thank you for your help
