@WVduckchick Thank you. There is part of the membrane on the right removed, but the bottom left has oil on it which is why it is a funny colour i think. I think i might need a drink of wine before even thinking about the next step (hoping he just jumps out himself!) I will definitely start at the top if i can - the shell does seem to be covering a lot of his head? Do you think he could hatch himself at this point?
Anything is possible, but I kinda doubt that he would make it out without more assistance. Only because the opening is not quite big enough (its fine for now though), but there's no real way for him to zip off the part that will be in his way. I hope that makes sense. He will start thrashing and trying to make the opening bigger, and he might be able to, but I suspect he will just bash around at the air, and not really break much more off on his own. That's why I said it will help if you remove a little more above and below him, then when he is ready, he will shoot right out.
When you get ready to do it, if you press down gently on his bill, he may stretch his neck out and "untuck" his head from under the little shell cap. If so, then he's close to being ready, and may even kick the bottom of the shell off, right there in your hand. So be prepared! lol If the head comes out and he doesn't kick completely out of the shell, just place him back in the incubator like that, and he will eventually kick the bottom off.
