I've hatched duck eggs before but this is my first time with chicken eggs. They went in the new incubator at 2:00 p.m.on March 5th. Going by hours, that puts us half way through day 22. No wobbling eggs, no pip, no noise. I did, reluctantly candle a few yesterday and noticed some movement in a couple eggs. Humidity is at 65 and has been since day 18. Should I be worried or just keep waiting?
