We seem to be having a lot of trouble getting chicks to hatch. When we candle them can see the veins and the heart beating and they move, but then they never hatch. They die in the shell. Next to last batch, 2 pipped but they died before they could unzip. One was alive for a bit but I had helped with the zipping. It got out but died right outside the shell. I think my son has the temp up too high. How hot do you suggest it should be? What is the hottest to the coolest to keep the heat at a regular temp? One lived out of last batch and I really wanted her. Roo was a Spanish Barque. She was 3 days old but I found her dead this morning in the nursery box. Our % of living and hatching is way down. We keep plenty of moisture in the incubator too. Any help would sure be a blessing. We were told by one lady that this is the wrong time of the year to try and hatch out our eggs. We had 2 green eggs and when we candled them could see the heart beating and they were moving but then they never hatched. Waited tho to see if they were later than what I had counted the days for but now one is oozing which means it is now rotten and dead. The eggs were from a friend who has health certificates for all her chickens and the Spanish Barque is a registered roo and I guess very rare. We were looking forward to getting some good babies from him and his flock. No such luck. I just think heat is too high. Son has it set at 100. Think we are frying the eggs in the shell. Thanks for any advice.
