Here's an update on my second attempt; there was an area wide power failure here in Palo Cedro, CA that lasted approximately forty-five minutes. My incubator is in my metal shop building and the temperature was probably around forty degrees at the time. I had no way to maintain the incubator's 99 degrees. I did leave the eggs incubating after the power was restored (even added an extra five days gestation). Sad to say, there were zero chicks hatched.
My previous effort only produced ten chicks and three of those died within the first three days. Three others had splayed legs. After treatment, only one was cured. The other two both have a leg extended in front and one to the back (like a hurdles runner). One has discovered he can move around by flapping his wings; the other one kind of humps along. In the last couple of days, one other chick has a kink in her neck. She does eat and drink but most of the time, she is looking straight up. (I thought at first she was trying to catch bugs around the warming light).
