Is it possible to have high humidity (75%+), but the membrane dry out if it takes the chick a really long time after zipping? I have one chick that has been completely zipped and stuck for 36 hours. That is, 36 hours of being zipped all the way. He is obviously breathing just fine, so I am guessing he can just hang out that way until the rest hatch, then I can lift it off for him? Also, I have another that seems to have a thick membrane. He zipped completely, but it's like he had to zip again through the membrane itself. He's been shell-zipped for over 12 hours, but can't get the membrane to break loose. I can see him breathing, but I doubt he will be able to get that membrane to budge. He has poked many holes in it, so I am guessing he will be okay until the rest have hatched? I am being SOOOO good at resisting the urge to help, but these two are obviously fine but stuck after zipping. *sigh* What do you think?
