be sure to candle the pointy end look for clear end- if so too much water don't lock down yet- I lock down at outer pi- then I know they didn't drown.
They all look dark and solid at the bottom of the eggs.. there is just a bit of liquid at the top that is still clear. I could see toes moving around in one.. so cute! its just the air cell seems to small. what is outer pi- ? I don't want to add water if it is going to drown them but then I don't want to make them get stuck if the humidity is to low.. maybe add water on day 20 instead of today (day 18) ? (or if they pip sooner)
