egg colour genetics

[pekin queen]

hi so i have a question about egg colour genetics: what happens if i cross a belgium bantam hen (of any kind) with a welsummer rooster and the other way around (and if you have any pictures of your chickens or eggs from this cross pleas post them) thanks

I don't have a Belgium bantam (sorry), but I've done a lot of crosses and understand egg shell genetics.

If typical, your Belgium will be off-white, cream. That means she will have very few brown genetics to contribute to the cross.

If typical, your Welsummer should be a darker brown. There are 13 genes involved with the brown wash over the white shell. It's hard to keep those lined up for dark brown.

My personal experience is that when you cross 2 different colors (off-white) and brown, you get a mid-tone between the parents.

So my best guess is tan to RIR brown IF your Welsummer is a dark brown. The lighter your Welsummer's color is, the lighter the cross will be.

Not that this gives you the cross you want, but it does show the crossing results. (I get green when I breed brown wash genetics, from my Barnevelder, over blue shell genetics, from my CL line). I've done a lot of Barnie/Cal Grey (white) so that's when I get the lighter tans. My Barnie color is about the RSL or Splash Marans dark terra cotta. That bred to that produces similar. That bred to lighter (like Cal Grey white) produced a light tan.

@Weeg !

Thanks for the tag! I don't know that much about egg color genetics, but I'm happy I saw this thread since I definitely want to learn!
If I'm going to be doing breeding projects with EE's, knowing egg color genetics is pretty important.

Egg Color is a Polygenic trait and a few of those genes are sex-linked in nature. This means that a reciprocal cross between a White Egg breed with a Dark egg breed will yield slightly different shades(Dark egg male x White egg female F1 will lay darker eggs)
