You can breed a white male to buff females and only keep the silver based females.

Christina, The silver base birds, can they be distinquishable on the day old chicks possibly by their down color?

Okay ya'll have made my day. THANK YOU. So I'll cross her over my Cuckoo roo. That is great to know. Also I have eggs coming from Dave jr, should get them Wed. She is out of BBS. Renie hatched her. I hatched another just like her and one with two little blue spots above its eye. VIVI

I didn;t realize she was really a splash if so you will only get blues and blue cuckoos and some may be split white. You can still work on the whites with her but the outcome will take a few more generations. I think Gayle may have been using splashes with her whites and maybe she will be able to help you with the procedure.

The breeder that had the BV White at the Orp Nationals this year said that he couldnt find any good whites when he got started so he found the best whites he could and crossed them to buffs. Can you improve whites by using Buffs??

Jon... what happens to color when this cross is done??

I haven't done it... yet... but I believe that the offspring would look similar to what you get when you cross a black bird with a buff, so its a muttled black and buff color, I personally would just cull for type at that stage and then take them back together and you should get some either solid white or predominantly white from those crosses, the hardest part would be getting the brassiness from the buff out of them.

It will determine what color is under the white Orpingtons. Help me out folks remember genetics is a challenge not a burden!!!!!I agree with Jon if the white orp is recessive white on E Black and cross to Buff, the white will be knocked off and you will have a bird with black and gold carrying (hiding recessive white). But not all recessive white birds are recessive white on Black. Some whites are recessive white on silver eb (silver partridge) and some even are made with incomplete dominate white added. If this is the case if you cross a buff rooster on a recessive white (eb silver Partridge) hen, you will have a sex linked cross, your rooster will come out silver and the hens will come out Buff (each rooster and hen carrying a copy of recessive white) and they most likely will have black markings. Now if you switch it around and put the silver based rooster on a buff hen, your hens will come out silver and your roosters will come out silver carrying one copy of gold. and each carrying a copy of recessive white. Now when you breed the offspring back to each other some will come back as recessive white. Or you can breed the offspring back to a recessive white bird. Now there are recessive white that are on black birds with the sex link barring gene. The question is do you know what your white birds are hiding? ?

There are breeders who claim that breeding splash into white will clean up the whites, most likely it will tone down the black that break though on whites. But from what I've seen incomplete dominate white will do the same.
Recessive white on splash should work well, the only thing you would have to contend with is the blue legs which is caused by the id+ recessive sex-linked dark shank gene. but that same problem occurs when breeding recessive white on black.
One breeder stressed use only roosters with lite shanks on dark shank hens: a true lite shank rooster is Id/Id and crossed to a dark shank hen id+/- all the females will hatch out with Id/- lite shanks and the roosters will hatch out with Id/id+ lite shanks carrying/hiding one copy of id+ dark shanks. Now if your rooster is lite shank carrying one copy of id+(dark shank) and breed to a dark shank hen statistically half of your hens will come out with lite shanks and the other half will be dark shank. and you also will have half the roosters come out with id+/id+ dark shanks and the other half Id/id+ lite shank hiding the dark shank gene.

Now if you were to cross a splash rooster on white hens. One breeder stress: If you rooster has dark legs shanks
Cross your splash rooster on a white hen with lite shanks. Then take a young male from this cross which should have lite shanks carrying one copy of dark shanks Id/id+ and breed it to a hen with lite shanks. Then from this only use your birds which come out with lite shanks to develop your line. And of course if you have some nice robust hens with dark shanks keep them in a separate pen and continue to breed them to lite shank roosters.
Id = dominant sex-linked lite shank gene id+ = recessive sex-linked dark shank gene
Roosters can carry two copies of a sex-linked gene. Females can only carry one copy of a sex-linked gene.
(Id/Id) lite shank rooster (Id/id+) lite shank rooster hiding a dark shank gene (id+/id+) dark shank rooster
(Id/- ) lite shank hen (id+/-) dark shank hen since the females only have one copy of a male chromosome they can only carry one sex-linked gene.

(B) Dominant sex-linked barring gene will inhibit the dark tissue pigmentation, it is a black inhibitor. And will help to tone down dark shanks, but hens can only carry one copy, so you may find cases where the female legs may be a tad darker even with the sex-linked barring gene. So if you can get the (Id) dominant sex-linked light shank gene and the (B) Dominant sex-linked barring gene going on the same birds that should help lighten the shanks.
I think they found this when they tried to make cuckoo Silkies, using the sex-linked barring gene, lightens the dark blue pigmentation on silkies.

Thank you, it is not often that another nurse can stump me. So excited to be working with color genetics again.
