Pointy end of call duck egg is clear

[Laura Rees]

Hi guys any advice would be great. I have a broody hen who is sat on a call duck. It is day 19 so I thought I'd candle the egg. When candling the egg everything looks normal I see veins I see movement but the concern I have is that on the bottom of the egg (opposite the air cell) there is what I can only describe as a clear spacing. Does anyone know what this means and will my little guy hatch?

All is normal. Duckling just has not developed enough to fill that space of the egg.
