John (1) Does not recessive = hidden? I can see the white so I would think that it is dominate If it is hidden how can I see it.
Recessive is a relative term used to describe the relationship to another allele termed the dominant allele.
That traits of the recessive allele will only be shown if the person has two copies of the recessive allele. If a dominant allele is present, then the recessive trait will not be shown. The definition of recessive gene is a gene that is hidden when a dominate trait is present.
when there are two copies of a recessive gene then it can make its appearance. all recessive genes need two copies to make their appearance. if there are two recessive copies there is no dominant gene/allele to block it out . If you have one dominate gene and one recessive gene. Then the dominant gene will make its appearance.
But dominant white is incomplete dominant and does better with two copies, there are other genes that can dampen one copy of dominant white.
Your white Orpington was a lavender which is covered with recessive white. Recessive white only white washes a bird, it dose not change the color of the bird. Since you breed the the white covered lavender bird to a lavender you knocked the recessive white off your white orpington (which had a lavender bird underneath). and of course there is a sex linked baring gene involved which put barring on you lavender. All recessive white birds have some other colored bird underneath the white. so next time you see a recessive white bird, you are seeing a colored bird which has been white washed. Most recessive whites have black birds underneath. But there are lines of recessive white with other colors underneath. Now dominate white works totally different it is a diluting gene and alters the color of the bird.
crossing this white rooster (lav gene and cuckoo gene) with a white hen (I do not know whether she is recessive or dominate) will give me? I see white on them but will they carry either one of those (what I call hidden) genes? John
If they are orpingtons most likely they are recessive white. If you breed recessive white birds to each other they will continue to be recessive white, regardless what color they are covering. Have you figured out what sex you lavender cuckoo is. If it turns out to be a hen breed it back to the rooster parent. If the lavender cuckoo turns out to be a rooster mate it with a black or white hen. If you get lavender cuckoo from this cross then you know the black or white hen was recessive for lavender. But if you get all black chicks from this cross a percentage of them will be barred carry the recessive autosomal lavendar gene.
so to find a bird with recessive white you need to do some test mating, if you find a bird thats completely white mate it to a black chook and if any of the offspring are white (they may have some black flecks with possibly gold bleeding through in the top part of hackle) you know that the parent bird is dominant white, which is what you dont want, you need to find a white bird that will give only black or black with barring offspring when crossed to a true breeding black bird. the other way to know if a bird is recessive white if it pops up from a black pen with only black parents, therefore since you know that recessive white is recessive then it lay unnoticed in the parent birds.
Update on CUCKOOS. VIVI and Irene got their full brother to my 2 breeding males. As some of you may know, I was very lucky to get some Cuckoo eggs from Harry 4 years ago. This was before I had and Whites. Then Harry shipped me one fantastic White Orp last year. Both his Cuckoos and Whites has size from Ammarell lines and Moore lines. So many now like these Cuckoos, VIVI got her Cuckoo cockerel, who is brother to my two. She told me she was offered $200 for that bird. I told her she is free to do with him what she wants. Well, VIVI being a good hard working breeder knows what is inherit with these birds. She said nicely thanks but no thanks. I plan on getting her one more Cuckoo male to play with this fall. I now am exploiting the inherit size in using my breeders with first my 2 Pontious White pullets then now the BEHEMOTH is in with some of my lesser quality Blacks. The genetics with the Cuckoo gene is a fun one to play with. When breed to a solid Black or White girl, provided the girl has no Cuckoo in her genetics, will throw solid White & Black pullets, and all the boys will be Cuckoo. Well, I have about 8 or so Cuckoo cockerels I have hatched. The first wave was from the Pontious Whites. First is a pics of the 2 boys who are part Shaffer lines that I crossed with a Korfus/BUSTOFF Blacks (BUSTOFF is what I call a line of Blacks I made from breeding a solid Black Meyer Hatchery mutt mix cockerel, part Australorp and part Ameraucana with who knows what else, over gorgeous Akers Buff hens 4 years ago. Larry Lee, my buddy here in Indy, gave me these fantastic Buffs. He said to see if they were able to throw fertile eggs, it was his idea for me to use my horniest male. The Meyer hatchery mix. Thus, BUSTOFF was made. Needless to say BUSTOFF was 11 lbs at 11 months old). Since then I have made tons of different varieties that are not seen around here. Shaffer Cuckoos with a little Korfus/BUSTOFF in them BEHEMOTH, Very close to 12 lbs, if not more. Harry wants me to weigh him. I need too. You can see how big he is by looking at the standard size livestock fencing, which has 2' by 4' sections.
His little brother Ralphie. Ralphie is in with another BUSTOFF line hen who is a Dun Birchen.
One of many sons of the BEHEMOTH. He has a nice top line which both my adult males have. I like Ralphie a lot. I think he maybe a Dun Cuckoo by the looks of him which is why I have him in with this Dun Birchen hen
This is a pic of the son from my breeding a sister of my Cuckoo line to a Dick Dickerson Cuckoo Marans. Fun thing about the BUSTOFF line is I have been getting one RUMPLESS bird each year now for 3 years strait. These oddballs seem to have 2 weird genes combined at a time. So, I got a Rumpless Black Bantam last year that I gave to Larry Lee. This year I have the MONGOLOID, aka MONGO. As you can see he has the feathered shanks from Dick's Cuckoo Marans cock. And has the enormous size that is now inherit in my Cuckoo line. He is one wild looking boy.

I was going to say, cull that last cuckoo, than I realized he was part Marans lol.....are you going to use him?
lol No, he and his mom may get sold on CL. I am culling hard with what I have. I have 3 decent Cuckoo cockerels, which are White splits. Harry says I should take my Columbian boys back to Cuckoo to make a line of Columbians. I will also take them to Whites. I really like the front on this male. The pullet is from my crossing my 13 lbs Cuckoo cock onto some of Gayle's old White line hens I hatched from last season. I may play around with them too.
