I woke up this morning to a perfefct hatch, these were my eggs and did a dry incubation for 18 days. No turning the first 3 days to set the air sack. Used turner and forced air at 100.5. These eggs were dipped in 2 tlb. oxine in one quart water before I ever placed them in the incubator. At day 18 I put them at 65% humidity, Humidity is not the same on each shelf, it ranged from 65% to 70%. I never open the doors or touch once I began and this morning I woke up to a very clean and one day early hatch. I notice the Silkies on the other shelf and now making little hole also. No shrinking or drowning babies and hatching in paper egg cartons with bottoms cut out. I see this way the chicks are not rolling the eggs around once they are out. Happy Hatching........the only way is this way, so happy.
