I started with 6, 4 quit day 19 or 20 Ihave no idea what happened. Temp was steady @ 100.5 entire time and humidity was in 69 - 74 % range. I candled on 18th day as I moved to hatcher from bator and all looked great. Anyone have any idea what I may have done wrong? Anyway...here's some pics of the 2 Silkies that did hatch.
