I had 6 silkies hatch on Friday night into early Saturday morning. One egg didn't do anything and I was ready to give up on it. Well a few minutes ago it hatch a lovely little splash. So I started with 12 eggs. Three were infertile, 2 didn't go very far. When I broke them open it looked like scrambled egg. So I had 7 left and all 7 hatched. That gives me a 100% hatch. Not bad for my first time in my home made incubator. However I'm exhausted in last 21 days I haven't slept more then 4 hours a night. And the last two night of the hatch I slept maybe 2 hours a night.
