Over the past few weeks, I anticipated my eggs being shipped. At that waiting period, I made an incubator, got a thermometer with a hygrometer. My first thermometer and hygrometer broke and i needed a new one. By the time I got my chickens, the thermometer and hygrometer didn't work anymore. I had to incubate the eggs without one. The fifth day of incubation, I got a thermometer and I noticed that the eggs were at 109 degrees Fahrenheit. I'm a new chicken raiser and I'm not sure if the eggs are dead. When I candle my eggs, I can see a dark mass in the middle. Two of the egg has a dark mass but also a dark spot on the bottom of the egg. I'm not sure if my eggs are dead or not. Is it possible for my eggs to survive that.
