That's so great! 75% with still air and a staggered hatch is fantastic! I almost never had hatches that successful when I was using my Hovabator.Just eggtopsied 3rd egg. Looked normal. For whatever reason, it died with head to the side under wing. This would have been the proper position before the last push to break thru the air cell. No wonder it didn't pip. Still, it's good to know these things & I'm pretty proud of my 75% hatch rate! With a still air LG & staggered hatch & being a newb!
I have 6 healthy, beautiful chicks! Will post pics for Monday!
This was my first hatch with my Brinsea, and I hatched 90% of the eggs that made it to lockdown. This doesn't count all the eggs that were clear and never made it to lockdown, but still. That beats my previous record! I love this incubator.
