I have silkie eggs that are at the end of day 20. I don't hear any chirping and none of them are piping. When I candled at day 18 I was not 100% sure they were still viable but they don't smell so I locked them down. I want to candle them so bad to see what is going on in there. Should I candle them or just leave them be? Shouldn't they be piping by now since they're going into day 21? My temp has not stayed constant 100% of the time. I found at night it would drop to around 96-98 and I would have to keep getting up to adjust it and a couple times it got too hot 101-104 but not for very long.
