15 silkie eggs and 3 babys hatched. I opened some of the others. The babys are fully formed but dead. The sac is NOT broke and air chamber is probably 1/3 of the egg. No pipping either. GQF sportsman incubator set at 100 and temp on shelf 99.3 to 99.8 Humidity is about 55%on petsmart hygrometer and GQF wetbulb shows 82 deg(the original water tray kept full) one top and one bottom vent open. The incubator is in my air conditioned office. I should have chicks everywhere! I just bought 14 peafowl eggs yesterday. Wish I could figure this out. Folks that use a sportsman talk to me. What do you do? These eggs were shipped but fertility was great. If the environment is good enough for 3 to hatch why would the rest die in the same tray on the same shelf in the same incubator?
