From now on and all future i'm never ever going to use a incubator again.
I took 4 of the egs in te incubator and they all collapsed. The other 4 eggs i incubated in a Tupperware box filled with moistened vermiculite in a cabinet at my bathroom for 9 months with a constant temperature and it worked like a charm. Now waiting for the 2 other eggs to start sweating.
And then there was number two hatching.
It started to hatch at the top of the egg, so i guess that is not normal and i decided to help the little fella out of the egg.
