I have one Silkie Egg on day 23. Candled and don't see internal pip but might see movement. Water test shows slight tremor or jiggle. Jiggles a bit when it hears me chirping. Humidity is good. Temps were maybe a bit low during the 21 days, but not serious. No external pips. Getting anxious. Read all info on assisting, but not sure if needed. Advice would be appreciated.
