I don't think anyone in here is opposed to intervention; I know I'm not. In fact I'm helping someone else with another assisted hatch right now :) But it is possible to make mistakes and do things like get overzealous and open an egg too early. No one should be berated for that, but the mistake...
Yep, definitely opened the egg too soon :( That's why we were saying in the other thread not to open the egg any further than an external pip.
But, don't panic, we can take care of this. Put her back in the egg shell and put her upright in a cup that she can't move around in. It needs to hold...
