Remind me please - breeding blue

[Casey76]

I've been out of poultry keeping for a long time, and my genetics are rusty.

I've found somewhere selling Silver/Blue Marans hatching eggs. Can someone remind me the possible combinations I could end up with if it was SBxSB?

Thanks!

Blue is a modifier of black. I’m not sure if the correct terminology is incompletely dominant or partially dominant but two copies of blue give you Splash, one gives you Blue, and none gives you Black. This only effects the feathers that would normally be black.

If you cross two blue birds, the odds give you 25” Splash, 50% Blue, and 25% Black, but that is only the odds. In real life I find you have to hatch a lot of birds for the odds to mean much.

Welcome back to the dark side. This stuff can get addicting.
