If mauve, the Lav Roo didn't sire - as both the hen and roo are genetically black.
For the same reason, if the BBS Roo was Black, cannot be mauve.
In either of these two scenarios a choc rather than mauve chick would a possibility - but if neither roo is split for choc only a pullet could show choc or mauve but a cockerel would be split for choc.
Believe your BBS Roo (either Blue or Splash) is the sire and the chick is blue cockerel split for choc.
It's not letting me post a pic of a mauve.
It's been some time since you posted - what did the chick turn out to be?
Hello,
I'm still learning my way around the genetics. I thought I had read that a Blue Roo Over a chocolate can create a Mauve?? Since the Lavs are out, it either has to be my Large Black (Angus) who is possibly split to chocolate or one of my BBS Roos. I've separated Angus now with some black hens to see if I can find out if he's split to chocolate.
Unfortunately I lost my little Mauve in our heat recently :-( BUT I DO have another being raised by a broody, though I wouldn't necessarily call it a Mauve.......Looks more like a lite mocha--I will need to post a picture.
Aww sorry you lost your chick. It's always the "special" ones that something happens too isn't it?
Lets see if I can help clarify for you.
Assuming you know how BBS works. BB = black Bb=blue bb=splash
Black allows Choc to fully express itself so a choc bird is also a black genetically, same goes for Lav. This is one of the reasons why black birds are so valuable in breeding programs.
. .
Blue and Splash partially bleed over choc to create mauve - if you look closely at mauve feathers they are actually blue with choc edging.
So crossing a black roo with a choc hen is like crossing 2 blacks - you will get black pullets, black split to choc(cockerels) and choc (but only pullets unless your black roo is split to choc). Blue, mauve and splash are not possible with 2 genetically black parents.
With a blue roo and choc hen Blue, Black, choc and mauve are possible. Males will be split to choc.
Splash roo and choc hen - Blue and mauve. Males will be split to choc.
Choc is a sex linked gene. Males have a gene pair but females only a single gene. This means males can be choc/mauve cc OR split Cc, not showing it but able to pass it to offspring. Females either are c~ or are not choc/mauve C~ if they don't show it they can't throw it..our
So, since you know your choc hen (black) laid the egg the roo had to be either blue or splash in order to produce a mauve.
He would not have to be split for choc to produce a mauve pullet. He would have to be split for choc to produce a mauve cockerel.
Thankyou for taking the time to reply and clarify, it is now--clear as a weak cup of black coffee
As I suspected it's one of my blue boys (Dallas and/or Cowboy) hahaha
I also have some choclates, but not sure their sex yet. Also, when my Large Black Boy (angus) was running around he was visiting their pen too--so I'm beginning to think he "might' be split to chocolate. FancyChick (Nellie) sent some "boxwarmers" with my chicks and said if they're Cockerels the MIGHT be split to chocolate, otherwise if pullets--then they're just black. I thought by putting Angus with some black hens, and it he was split to chocolate--then there was a chance he'd throw a chocolate pullet? And that's how I'd know for sure. whew! lol The other little Mocha/mauve chick I have is much lighter than the one I lost, I will need to post a picture.
Changing the subject....@ Eden Camp....would you happen to have LF Silver Ameraucanas? The ones in my chick order from John Blehm ended up being cockerels, looking for a couple pullets. I did get some nice Lavs and Blacks
If a boy is split you can get choc/mauve pullets out of black, blue or splash hens. Hens cannot be split. So the sure way to find out if he's split is to breed him to anything BUT chocolate. If I remember right the boys have some chance of also being splits. Bred to the choc hen and you get a choc cockerel then you also know if he's split - and you will get lots of choc pullets and all the boys will be choc or splits for sure.
If the chick is VERY light there is such a thing as mauve splash as well..........
Can't help you on the silver but I'm on the hunt for Lav English Orps and Ams...........hen,pullet or a few chicks or eggs.
Lost the girls and I'm sitting here with 2 Isabel Orp roos!
I have him in with some black hens, so we shall see. I do have Lav Eng Orps, everyone is just starting to lay and all my orps (except for the blacks) are running together right now, I've been hatching pure orps but mixed colors if that makes sense. hahah I've BBS, Cuckoo Lav, black cuckoo, Lavs, Jubs and LF Chcolates and Med. Chocolates (not projects) I love my chocolates! Oh and I have Spangle/Mottle, reds, white.....I did loose about 20 English Orps in a week due to our heat. I think what's left are adapting now.
I also have Amer. Lavs and pure blacks, silvers, from John Blehm and I also have some Lavs splits and black split to lavs with double muffs. These are about 4 months old now.
I'm still getting everything sorted out, but it sure is fun hatching my blended English Orp eggs! lol lol
Oh where did you get your Isabels from? Do you have pictures of them? Are they Isabel Cuckoo's or just Isabels?
Have you used the genetic calculators available? Can learn ALOT from them!
Oooooh nice collection of birds! Can I be your friend? LOL!
Imagine with the blended orps running amuck hatch day must be like Christmas! Some awesome genes to play with there!
My primary focus is Silkied Ameracauna. Choc/mauve (chooschicks), BBS (Catkai), projects planned for Lav, Jubi and Crele flavors too.
I lost my lav AM hen in the heat
Do have a solid black AM roo Smith/Bhlem anda rverse trio of black/lav splits.
CCLBsI have a blended flock frm 3-4 sources and adding 2 more from eggs shortly.
BBS/Copper and maybe choc/split Marans coming out. Several Breeding Pens.
BR aso maybe choc coming out.
Have Rhodebar pullt and eggs to hatch.
Have Konza Prarie Rangers (another CC project) Breeding Pen
Sulmtalers, wheaten now and Gold wing eggs in the bator.
Now for the Orps...
Breeding pen of English Orp - mauve project. Black and blue roos split for choc over blue hens, so I get choc and mauve and splash .
The pair of Isabel roos in with a heritage buff and black and think the barred hen is going in too .
Jubi hen and a dozen eggs hitting the bator.
Crele eggs hitting the bator.
Lav Orp eggs soon to arrive
a few Mottled/split to black eggs soon to arrive
And a few Ayam Cemini eggs coming......
Haven't gone NPIP yet as didn't want to limit sources building my breed foundations. It's a nuisance really, so your eggs don't have salmonella if you want to eat them. Big Whoops!
Next year suppose I will. Next year should be all kinds of fun! At that point maybe some wild orp genes to play in projects with to add but pretty well set to plug and play. .
Ok, this is going to be a GREAT day! My Lav/Split/Black pen ajoins the porch and with the heat, I let them have access under it. They go under there to escape the heat ad I know the girls had started laying there instead of the box. No whoops as I was focused on hatching out SiAms and didn't want to confuse the two - would "get around to it". Well, all of a sudden the Lav hen stopped coming out at feeding. First day or two I figured she just was in the middle of laying. Third day (yesterday) no sign and I'd resigned myself that she must have died under the porch but I just didn't have the heart to crawl around under there quite yet. Well Glory BE! I go out to feed this morning and out she trots with 9 little ones! The Black Smith/Blehms roo is dominant and no lavs chicks (other 2 boys are split) so I have a bunch of Black split to lav chicks instead of losing my only lav! Bless her beak she brooded 9!!!!
! This is her as a grow out.
