If I put my eggs in around 8AM I count the day I put them in as day 1 on the 18th day which counting that way would be Oct. 13th and I normally candle them when it's dark in the evening make sure they look okay and up my humidity to 65% and wait. On shipped eggs I've had Marans take 22 days to start pipping even if I don't count the first day. It's so exciting to hatch eggs I'm wanting to get some.....I have to wait for mine to get old enough.
