Thanks for sharing your experience! Sounds a bit like mine.
Day 26 and no signs of life. We will open the shells tonight and see what's inside. I do see blood vessels in the membranes under the air sack while candeling. My daughter is heart broken.But we will try again with local eggs or chicks. Thanks everyone!
I dont know if youve already opened them, but when they're questionable, break a small hole through the air sack, then gradually head down to the chick area. It'd be a bummer to break through a blood vessel on a live chick. If you go through the air sack, you can gradually see how it fared and if signs of life exist, you can pop it back in the incubator and crank up the humidity.
