Get this I candeled before lockdown and the eggs were all showing great developement. I came on one egg that was cracked so i put it in the egg crates I have in the incubator. My son says I think I heard it pip, so I asked him to turn on the light and would you believe it I had 6 pipped eggs that I had not even noticed so we quickly reloaded them into the bator and locked it down. I hope I did not srew up my hatch! Has anyone ever had this happen to them? By the way today is day 18! I love this Gensis 1588! it has been almost a set and forget hatch with only adding water every 3 ot 5 days.
