I've read until my eyes feel like falling out, but hope to get some answers. I had the incubator 1588 full of Silkie pullet eggs (their first) for experiment, EE eggs and Ameraucana shipped eggs. All were doing fine on day 18, air cells, temp,, humidity were as they should be, auto turner. I was doing the Dry Incubation method and worried the Silkie eggs might not have enough humidity. The Silkie eggs hatched fine much to my surprise since the roo and hens were not even a year old yet. The EE's hatched fine. But the Ameraucana eggs didn't hatch and on day23 we saw no movement, did the float test, it was positive so we left them in the bator. today day 24 we saw no movement on candleing and opened them all for eggtopsies. All were beautifully developed but dead. Two were starting to smell. I doubt they drowned with internal pipping the air cells were right where they should have been.
Anyone have any ideas of why?
