I think you're right. If I breed her to a black/split lavender roo what would I be likely to get?

IFF, she carries lavender you might get some pure lavender chicks. Half the chicks will inherit blue, and even if they inherit lavender, you will not be able to tell. From the split, half will inherit lavender. Of the not-blue chicks, only those that inherit two copies of lavender will be lavender. There will be absolutely no way to determine which, if any, of the black or blue chicks are split to lavender. Won't even be able to tell for sure which of the blue chicks are pure for lavender.

Disagree. There is no way to tell that that blue bird carries lavender at all.

Would the good ol trusty "rachis of the wings test" work to tell blues from lavs in such a case? I've always wondered that

It was early i thought she said if I breed a split to lavender.. not blue to lavender.

It is that simple IF YOU KNOW WHAT YOU HAVE. Full lavender to full lavender gives you 100% lavender.

You are both correct

You are using the term as in a self-lavender that does not carry any additional modifiers (such as blue). She was using the term in regards to a bird who is pure for lavender, but may be carrying other modifiers as well.

As a gene, lav/lav dilutes black AND gold pigment. If the base colour of the bird is solid black, you will have a lavender bird. If the base is NOT solid black, other modifiers are present that will alter the appearance (for example lavender cuckoo or lavender partridge as was mentioned earlier). Easier to pick up on gold or silver pigment modifiers than when additional black pigment modifiers are present.

Sonoran when you say
Take a partridge and breed in two copies of lavender, are you talking about doing this to get porc?
Could you explain this a little more?
Thanks

Nope. A bird who is lav/lav and Bl/bl+ carries the characteristics of both.

No, to get lavender partridge: a partridge-patterned bird with lavender replacing black pigment and isabel replacing gold/red pigment

Porcelain does not have penciling, and should have mottling.

I should probably have noted that not all the offspring of a partridge and lavender would carry correct penciling genes, and this will persist into the 2nd generation when you might expect to get some lavender partridge. Especially if you breed the F1s to lavender instead of other F1s.

Sonoran, since I don't know whether my blue pullet is a split to lavender, would I be better off breeding her to a buff roo hoping for porcelains? Or, what would you recommend I breed her to? She is typey and perfect in all other ways (great temperment too) and it would be a shame not to breed her to something good.

Also, is 'penciling' parallel with the feather shaft as opposed to 'baring' which is perpendicular to the shaft?

How do you identify penciling on a silkie?(I did look up the references you gave me). Is it on the hard wing feathers only? I can't see it on the downy feathers.

Thanks....I had no idea what to call her. Now, what should I mate her with?
