Duck Genetics

[HollyParks]

Hello,

I lost one of my sweet black Indian Runner Duck today. Although I’m absolutely devastated, I’m holding on hope because I already had her eggs in the incubator and they’re developing.
My duck flock consists of Welsh Harlequins (including the Drake) and three runners (black, blue, and fawn/white). She laid blue eggs but so does my blue runner. How can I know which ducklings are hers if they are a cross? Is there a predictable color pattern? I’m more familiar with chickens. This is actually my first time hatching ducklings.

Thank you

So sorry for your loss

The babies from your Black Runner will all be solid black like her.
The babies from your Blue Runner will be half solid black, half solid blue.

So, any blue baby is not hers, and any black baby may or may not be hers.

Thank you so much! I’m so glad that I had already started the eggs. I appreciate your insight!
