Understanding the lavender gene

Yes, you will discover the imperfections if you line breed/inbreed. However, if you have a solid line you will advance your program greatly. Before doing any of this we have always waited a generation or so to see if anything popped out that was a fault. Right now I have a run of pigs that have been line bred for about 6 to 8 generations with incrediable results. We are finally outcrossing, but it could lead to disaster. Time will tell. Sometimes it is hard bringing in new blood. However in our case the line breeding has helped us avoid major problems as well and produced healthier and stock fitting the best of the Standard desired. It is all a matter of knowing your stock.

Someone should take the time to make graphics of the Punnett squares for this. Visuals make things easier to understand for a lot of people.

Well, if someone wants to help me write up the square properly... I will be happy to add graphics

So is line breeding in order here? Meaning taking offspring back to a parent possible to create your flock? I would think that would give you the best bet of more percentage of coloring you are working on. Is line breeding or any kind of inbreeding to create a flock a no no for chickens? I know in horses it is a no no, but other critters we have worked with it is a regular practice as long as you do not have a fault in that particular bloodline.

To get the lavender you would have to line breed. As with Orpingtons though it is hard to find true black lines. I have five true black exhibition lines and have been working on them to make my own line. It will be two years before I offer anything up for sale. It was like pulling teeth to get these birds, but was well worth it. It takes a lot of work to get the lavenders up and going. If you are working on the lavender silkies I would use a OEG bantam or a Belgian self blue. If you were working on LF I found a breeder in PA with lavender Old English game LF, there is also the Ameraucana in selfs that are LF. OR you can get some from the Hinks

when they off some up. I have three programs here to develop some diffrent colors in the Orpingtons. Its mainly for fun, I just love genetics. There is also a article in the practical poultry magazine on how Pricilla Middleton made her Lavender Orpingtons. The bad thing is there are no lavender leghorns here in the US, but you could use the diffrent one named previously to make the breed of lavender you want. There are just more caricteritics to breed out

I would love to see more people working together on this and other colors.

Thanks for this thread - have not read it all but interesting so far. I have 9 D'uccle babies. 8 Mille Fleur and one porcelain. What I had noticed about the mille fleur ones is that some of them have a blue tint in their baby down. Could it be that they are the babies of a Porcelain/ Mille Fleur combo or grandchildren with recessive lavender genes? I don't know if the porcelain has the same parents or not but they all came from the same hatch.

Ok, I've made a few punnett squares... I used L for lav gene, l for black, LL represents lav bird (2 copies of lav gene), Ll represents a black, split lav (1 copy of lav gene), and ll represents a black bird (no lav gene).

Hope this makes sense...

Here's an f1, lav (LL) x black (ll)

Here's an f2, lav (LL) x split (Ll)

split (Ll) x split (Ll)

split (Ll) x black (ll)

That did it for me-thanks!

Very nice Julie! Thank you.

Ok Thanks for the squares!

Here are some graphics

I hope the Split makes sense.... Wasn't sure how to show it was black with the lav. gene hidden

Ahh yes, with the drawings it becomes perfectly clear.
