]I am incubating some SILKIE eggs and Wyandottes, today is day 21 and only 1 peeping last night. This morning that peeping one was dead! And didn't hatch out at all, so I start checking the others in the bator, and all the others are dead! Didn't even start peeping! The temp is 99.5 and humidity is 65... When I opened them up they all had big yoke saks still! But dead ! I am so sad. I don't know what I did wrong? How long do Wyandottes incubate for ? Please help !
