I'm totally out. I candled, day 11, and all I got was glowing eggs and in the lighter shelled ones all I could see was yellow yolk swishing around in there. I took a leap and cracked open two, and nope nothing. I cracked open all 24 and NO development in ANY of them. My guess is that either my new incubator spiked and killed day 1 or 2. OR my Roo, while a great dancer and chicken stomped, is too young, 9 months old. I have seen bullseyes when using eggs for cooking... so who knows.
Bummed, but may set more. Waiting to see if the lady I was setting for wants them 10 days late or just wants to wait until later in the spring.
