Well, my hatch is done. Two healthy (but lonely) little birchen marans out of over a dozen eggs. Sadness.
It wasn't a problem with the eggs. They were from crfarm & DMRippy - they looked great when I candled them, & I saw movement in the SBELs. Couldn't really see movement in the Marans, but they looked like they were developing great.
Here's where I think I went wrong:
1. I stopped turning them a day early. Cuz I apparently can't do basic math. Duh.
2. I kept the humidity around 40-45% throughout incubation, which was good, but couldn't keep it above 70% for the hatching process. Not sure how I can improve that - it's SOOO dry in our house during the winter because of the woodstove! I even keep a kettle boiling on the stove all the time. It helps, but not enough.
3. I opened the 'bator once while they were hatching because one of the Marans was shrink-wrapped. The humidity dropped like a stone.
Sigh.
I'm going to do some more test hatches with my own mutt eggs before I try your nice eggs again. I gotta get better at the incubator thing!
Any suggestions on improving humidity? How bout suggestions on improving my math skillz?/?
