Lockdown day is tomorrow (Thursday) and all 4 eggs are moving and alive BUT I've been watching the air cells and doing a dry hatch since I felt like they weren't progressing and expanding like they should. Here I am ready to add humidity and kick it up for hatching and my air cells still aren't as big as they should be. Once a day mist has not made a difference and the humidity has been between 35 and 40 the whole time. I'm worried that these ducklings will pip and drown. Any ideas? They look like they are around day 15 for size instead of day 24 which doesn't leave much room for successful zipping. At this point I'll do anything! Thoughts? Insights? Experience?
