You know how I posted and said I was planning on doing some assisted hatching earlier (thanks everyone for the advice, by the way)? Well anyway, more on that now.
The chick has zipped around about a quarter of the egg, but like I said, hasn't made any progress for a couple of days. The membrane was completely dry, so we wrapped the egg in a wet towel and are leaving it in the incubator for a half hour or so (still waiting). But before we put it back I tried to help it zip a bit. Maybe it was because the membrane was dry, but I couldn't tell which was the shell and which was the membrane. After clipping away a little bit at the shell and getting some membrane too we gave him and put it in the 'bator.
Is this just because the membrane was dry or is it always this hard? Is it okay if I accidentally clip away a bit of the membrane?
It sounds like the chick is just stuck from the membrane drying out. If it was unzipping that long ago I can't imagine it not being ready to come out. I'm actually surprised that it didn't pass after waiting a couple of days! What a little fighter!
