Several have died because they couldnt get out of their shell. I have 6 that are hatched but had to help 5 out. The last one was bleeding. I candled the rest and two I could see very few veins. The rest looked dead. No movement in any of them. The few that died that were partially zipped had their beaks out, do you think they just over exhausted themselves? Temp 100.5 and humidity 71.
