Bresse Chickens

[tbird9]

I only a little about the white genes. THere are two. ONe is dominant and one is recessive.

I have dom white in my easter eggers. If I have a bird carrying red, it leaks thru on the girls as a cream color, with the neck a slightly darker cream. In my one boy that is one of these crema hens with a blue AM father, the boy was splatered with black spots and then developed the red in his back area with the black. OVerall he is white except for the bakc and wings.

recessive white require 2 rece whites to show. ANd that is the limit of what I know.

According to Genetics of the Fowl, by F.B Hutt, the La Bresse (I assume he's only talking about the white variety) have the dominant white gene (I), which is an inhibitor of black pigment. In over my head here, but I just found it odd that people might be trying for "splash" by crossing the white and the black since the dominant white gene would inhibit most of the black pigment. My point posting the previous photos and this video is that, yeah, sometimes you get individuals with noticeable black spots, but it's also easy to get individuals that look fully white.

Quote: Blue- black- splash go together = 2 black base + 1 blue gene = blue; 2 black+ 2 blue genes = splash; 2 black + 0 blue genes = black. This is what I see in my blue AMeracana pen.

Mixing white and black doesn't make a splash in my understanding of the genes. You get the boy that I mentioned above, though he had red in him also ( black and red, not a double black) so that leaked thru.

While OOPsies happen; I can't see the purpose of mixing the black and the white for production purposes ; and I wonder how the blue gene was introduced ? I would think another blue fowl. Takes several generations to get the looks of the original bird.

I guess I finally understand what BOb BLosl has been writing about all these years: no need to re invent the wheel when there are plenty of good wheels already made. ( THanks Bob.)

Here is my understanding of the blue/black/splash genetics: The concept is called Mendelian genetics, and involves two genes in an animal for a specified trait and only one gene from each parent is passed to their offspring.

BB=Black

Bb=Blue

bb=Splash

If you breed: BB x BB = 100% Black(BB)
BB x Bb = 50% Black(BB) and 50% Blue(Bb)
Bb x Bb = 25% Black(BB) 50% Bb(Blue) 25%Splash(bb)
bb x bb = 100% Splash(bb)

THere are two sets of genes involved and I don't remember the letter of the alphabet assigned to each.While the offspring gets only 1 set from each parent, the offspring has 2 of each. Except the sex chromosome.

B black r red
S for the dilution gene called blue S or s ( made up letter)

BB Ss blue which is a partial effect
BB SS splash
BB ss black

I crossed my blue ameracauana onto my red EE and my white EE. 50% blacks and 50% blues, and a few whites with other colors leaking thru.

To get the blue coloring into the bresse stock, another breed needs to be introduced into the gene pool that has the blue gene.

What is the adult size of the bresse hen and rooster? ANd what is the BW at the 16-20 weeks age?? THe three pound carcass is smaller than my expectation for a meat bird. OR do I neeeed to readjust my expectations??

Same principle, just different lettering. My B's are the same as your S's in terms of the dilution gene.

I guess I need to breed my blue copper marans to my Bresse to introduce some blue into the gene pool.....

GFF has already begun selling the Blue Bresse. There are photos on their website and an auction on RBA right now.

Mine were 3.5 dressed at16 weeks. They would be much bigger at 20 weeks.

That is big for a Dual Purpose chicken.

I will have to look at that......I'm not buying, but it might be a nice little project for me to think about. The marans/bresse cross would make a good meat bird, which is my interest in terms of production.

I processed a 20 week old Bresse capon slip. He weighed 4 1/2 pounds dressed, and was delicious!!
