Mottled lavender Orpington

VagabondFarm · Apr 26, 2016

I am very interested in starting mottled lavender Orpingtons in Canada, to my knowledge there aren't any here yet. And trying to find out info on the genetics involved, which is proving to be a tall order! So any help greatly appreciated.

I have access to lavender Orpington and back mottled Orpington (in my incubator now), but I can't figure out if you can use these two, or if jubilee is required. Also I beleave it matters which colour is which gender.

I can get jubilee Orpingtons if needed.

Shouldn't be too difficult to create, just will take a few generations to get started. Both mottling and lavender are simple recessive genes; the regular Mottled is just a black base bird with mottling added, and the Lavender is a black base with Lavender added. A simple cross of Lavender X Mottled will give 100% Black offspring, all of which will be split for (carry) both the mottling and lavender recessives. I'd recommend breeding the offspring of this cross to each other for the quickest way to get Mottled Lavenders; if you do a sibling cross (or non-sibling if you keep two breeding pairs of Lavender and Mottled), then 25% of the offspring of this generation will be Lavender Mottled. 50% will be split for mottling and/or lavender genes and can be used to breed back to their parents/siblings/other splits, and 25% will be simply Black with no recessives.

The chicken calculator might be of interest to you, it's very helpful, especially when working with simple genes like this. Does all the math so you don't have to.

Thank you. I have played with the calculator but didn't realize it would account for split genes. I will have to look at it again!
