I checked on him a minute ago. It appears he got some more shell open but now I don't see any type of movement at all, whereas before I could see the tip of his beak working at the shell. I'm, in all honesty, terrified to mess with him at all for fear I will cause him to die somehow.
i would pull the egg out and tap on it.. see if it peeps or moves around to let me know if anyone is still alive in there...
but I'm like that .. lol
