I have 12 white silkie eggs in my bator, today was day 17 at 2:30 pm it is now 5:30 pm. Tomorrow will be the 18th day at 2:30. Some people have told me with the silkie eggs they lockdown on the 17th day and some lockdown on the 18th day. Can anyone recommend when I should lockdown? This is going to be my first hatch and I am very nervous but excited at the same time. Thanks!
