Curious Question with Genetics

[Memaw karen]

I have a Chocolate Laced Orpington, I was considering places with two hens. One is “supposed” to be Lavender Mottled and the other Isabel Laced. So far all chicks from the two different blue/lavender have been mainly Lavender with some slight white showing through and a few almost a blue. What combination should I expect doing this?

I can't answer your question, but they are gorgeous.
@NatJ may be able to give you some insight.

I have a Chocolate Laced Orpington, I was considering places with two hens. One is “supposed” to be Lavender Mottled

Chocolate Laced rooster with supposed Lavender Mottled hen:

Daughters should show chocolate, sons show black while carrying chocolate. They should be color sexable as soon as you can tell chocolate vs. black. I don't know if the chick down color will be different enough to recognize, or if you will have to wait until they feather out.

All chicks should carry mottling but not show it unless the father also carries the mottling gene.

The chicks might have a black base color (sons black all over, daughters chocolate all over.) Or some of them might show some pattern of black & silver (sons) and chocolate & silver (daughters). It depends on what genes she may be carrying but not showing.

If the hen is really lavender, then no chicks will show lavender unless the father also carries lavender. If the hen is really blue, then half her sons will be blue instead of black, and half her daughters will be mauve instead of chocolate. (The blue/black and mauve/chocolate affect only the black areas, so that will not affect any silver that may show on the chicks.)

and the other Isabel Laced.

Chocolate Laced rooster with Isabel laced hen:

Should give daughters with chocolate lacing, sons who show black lacing but carry the gene for chocolate. Yes, that means you can sex them by color as soon as you can be sure which ones have chocolate vs. black.

Both genders should have a silver ground color like their father does, although I can't say whether they will have leakage of some other color as they grow up.

Both genders will carry the lavender gene but not show it unless the rooster already carries it as well. If he does carry lavender, then some chicks will show lavender lacing.

So far all chicks from the two different blue/lavender have been mainly Lavender with some slight white showing through and a few almost a blue.

I'm not clear what you are saing here. Do you mean you have bred these two hens to other roosters and gotten chicks of that color? If so, what color other rooster?

I’ll attach a picture of the rooster that’s been with the lavender/Isabel hens. I’ll also attach a few pictures of chicks that hatched from those yesterday. Thank you for your help!

These are from yesterdays hatch. Chocolate/chocolate pen, and the lavender/lavender pen

OK, that makes sense. Both parents show lavender, and so do all the chicks. Recessive genes are nice that way: once you have both parents showing the trait, all the chicks are certain to have it too. Yes, the hen probably is lavender and mottled, just like she is "supposed" to. I can't be sure whether she is carrying any surprise color patterns.

Those are really cute!

And it does look like both pens are producing the correct colors of chicks. That makes surprises less likely when you cross them.
