Ok so I am on day 26 of my "mystery" duck eggs. If they are the 28 day incubation type would I start to see a dip in the air cell now or closer to 28 days? I'm trying to decide if I should move them to the hatcher, or keep them turning. I am having a hard time seeing in the eggs. Is it possible to not be able to see movement at this point because the eggs are so full?
