Have 18 Silkie eggs and 14 SLW eggs in my Hovabator 1588. Tons of development with the Silkies but nothing with the SLWs. I'm only on Day 5. I am wondering if I was shipped unfertile eggs or if all the air cells were completely destroyed in these SLWs. Should I crack one open and see what's going on, or should I wait it out???? They are darker, mottled eggs...hmmmmmmm. Thoughts?
