I am incubating a selection of bantams and i have 9 out of 17 hatched successfully but it has gone really quiet now and i'm starting to worry. i have no more pips and the last one hatched 8 hours ago. When i locked down I candled them all and they all looked really good. I have 8 left that are doing nothing and i'm starting to worry they are all dead so I cracked one and it is perfectly formed all yolk absorbed, no blood, hasn't pipped internally or externally but is dead. I have been searching on here to see what may have gone wrong and don't know what to do. Do i open the others in the hope that something might still be alive? If i open the egg will i kill the chick, what makes them start to breathe? when do they start to breathe? or should i just wait and see if they do it by themselves. How do i tell if they are dead already? I have 9 beautiful babies but I am horrified at the thought that something i did (like open the bator or top up the water) killed 8 just as they were about to hatch.
