I agree...I've kept mine between 40-50, 50 max until lockdown then I'll raise it to 50-55. Soon as I start seeing pips or hearing chirps, I raise it to 60-65. Had good success w silkies that way. Btw I've learned through research that silkie eggs can handle a bit higher temp, so if something happens and you have a spike don't worry. You gotta remember the temp of the air doesn't necessarily reflect the inside egg temp so a little temp variations are ok. Also, silkie egg shells are almost like ceramic, a bit thicker. So humidity is key for a successful hatch with them. Happy hatching and good luck!
