Would it be safe yet? I'm almost positive I'll have to get him outof there or at least clear some membrane around top. When should I do that?
Lube the membrane with some Vaseline to soften it up. Those veins are really minimal, so I wouldn't worry about them now. Take your q-tip, and slip it under the membrane, next to his bill, and slowly, gently stretch it outward from the bill. I suspect he will start helping you by wiggling around. Once you get the membrane opened up and his head free, you should be able to shine your flashlight down his chest and see if there is any yolk. If he has any unabsorbed, leave him in the shell. If the belly looks good, just lay it back in the incubator and he will push out. Might even push out in your hand before you get to that point!
