My hatch has gone crazy too... It started with the duck deciding to go broody half way through gooses hatch. She kept taking eggs from goose, but she would spend more time off the nest. They had 4 ducks hatch on the 5th. On the 7th 2 duck & 2 turkey. They left the nest so I took the rest of the 45 chicken eggs out of the incubator out. (Zero hatch). I put the remaining duck egg and 3 turkey eggs in. Thought I would give them a couple more days. I candled that night. The duck egg was clearly stopped and dead. I pulled it. Last night I went to turn the chicken eggs I had put in there and there was a nice fluffy turkey. This morning I was moving some quail from one brooder to another and heard the tell tell sound of a egg exploding in the incubator. I smelled it before I looked. Thank goodness it didn't go on any of the eggs. I pulled them out and thought before I trash this last turkey egg I'm going to check it. I cracked open the air sack and it started chirping. I was about to sling it out in the woods. I wet a paper towel with hot water and moisten the membrane. No viens visible so I get membrane open at beak, wrap it in paper towel, and set it on top of brooder lid with incubator top over it. I rush and scrub bottom clean and get it and eggs back in there as quick as I can. I add the jars of water to up humidity and couple of hours later it looks the same still alive. All I can say is thank goodness I have a LF broody now to go with the 4 bantam. The hens do it much better than me. I may take the eggs from incubator and give them to her and quit for the year. Its been to crazy.
I put some of my eggs under a broody. She sure did sit tightly...... But she still didn't hatch out chicks for me. And, I only gave her eggs that were clearly developing well. One pipped and zipped but then stopped for so long it dried solid. I helped it out but it died. So, she got zero from the five developing eggs I gave her.
Bad hatching spring.
