. I have two dozen Guinea eggs in the incubator that I bought off eBay. They took 5 days to arrive in shipping and then I let them sit room temp for a day to recover. The eggs went into the incubator on June 11. Yesterday afternoon (july 5)one of the eggs hatched with a strong healthy chick. It had only been 24 days since I put them in the incubator. I hadn’t stopped rotation or started lock down. The rest of the eggs seem to be on track. Has this happened to anyone else?
