Don't give up yet! A local guy brought me 4 dozen guinea eggs he wanted me to incubate for him. He brought them to me around lunch time and I took them inside and sat them on the kitchen table to let them rest and adjust to the temperature difference. About 8:30 that night, I labeled them and put them in the bator. Three days later, I decided to candle them. I was shocked to find about 1/2 of the eggs were already very well developed, at least 2 weeks along. I just knew that they were dead, but as I looked, they kicked around inside the eggs. So, don't give up!
