I set more on April 18th. I did have it full of palm turkey (11) and guinea egg(9) eggs on April 8th.... just hours after I emptied it from my chicks pictured earlier. At day 9, the only fertile egg in the whole lot was a turkey egg. So, seeing as how one of the palms is setting on eggs (eggs from earlier than what I was incubating.. so they won't be any good), I threw it under her, and put 24 more mutt hens eggs in. That was kind of disheartning. Perhaps the birds are still abit young. I would think the guinea's eggs would have been fine. I have 3 males and two females in there, and they started laying eggs last November. They were hatched June 2011. Stupid birds.
