Hatching silkie eggs

[cmobley]

Today is day 15 for my silkie eggs. Do these usually go 21 days or 18 days. Trying to figure out my stop rocker day.

Why not split the difference and put them in lockdown on day 17. I hatch Bantam Cochins and that's what I do. Most the time they still hatch out on day 21.

Silkies take 21 days so lockdown would be day 18
