Mine was at 24 1/2 days and I had a dried membrane and it was not able to move to hatch. It DID pip though but that is all it did. Here is a picture of that chick after I got most of the shell itself off. And I added a pic of him today too
There is also a sticky in the hatch section which is what I followed and it worked perfectly
I did end up helping him all the way out and he did have spraddle legs but after I fixed that he was just fine and is now a wonderful blue orp roo
Good luck!
