My BCM eggs were supposed to hatch Wed, they didn't. I believe they are still alive, because I see movement in the eggs. Very subtle and sometime rocky like, so I know they are still alive. I haven't turned them. Are you supposed to if they don't hatch on time. There are no pips, What do I do? Should I crack them myself, will they die if they don't hatch soon. My temp has been 99.5 all along. I need advice.
