so far I havent seen any, seems that since is stilla a project and producing a good male is harder than females, you see all you have to do is to mate a choc male to a blue female... mating the blue colored males that carry choc(recessive) with the Mauve hens would produce alot of different...
all I want to know how to get a "Chocolaty" color Dun Based bird like the Dun based chocolate polish in this pic.
I'll get the chance to test this myself, as I believe I was able to obtain what I believe is a dun based barred cockerel, I'll mate him to a production red hen hoping for...
no they are not true chocolates, but they created a Craze in the UK...
I dont know if there is a project or not, but if I would start one I would look for similar sized birds to start with,
you should start with recessive chocolate gene if you can but if you cant use a Dun based chocolate...
there was a Craze on Europe because some people were importing "Chocolate" Leghorns from the U.S.A
but this "Chocolate Leghorns" were infact Dark Brown Leghorns which are based on the eb brown e allele and have very strong red enhancers...
this is how females look
this is how the...
sorry not all of them.. some look very slate dun color. Dun being an incompletely dominant gene is not as stable as the recessive choc gene.. so being in Heterozygous form will lead to different shades of Dun, one of them is Chocolate but not always.
this dutch boy looks nearly chocolate but...
while Dun can be made to look like Chocolate and make it indistinguishable from the "Real" chocolate gene. "Dun" is NOT chocolate and most of the time(when not breeding for it) will not look lke chocolate y will look "Dun". there are ways to make dun look like chocolate. but you wont get a...
some nice pics of the "Chocolate" Cuckoo maran project.
compared to Dun Barred
I know self Chocolate based birds based on Dun can look the same as Choc based birds, but this takes breeding and selecting for it. I believe once the Dun Cuckoo or Dun Barring breeders start doing...
if you have a Choc(Recessive sex linked chocolate) Rooster and mate it to a Dun Chocolate hen(dominant Dun I`D/i+)
this is what they will look..
50% of the males will look Dun chocolate(Dun I^D) choc and Dun chocolate can look identical(most of the time) they will carry the recessive sex...
blue can be improved upon.. the issue with blue is that other genes/diluters can affect its appearance..
check my light blue cockerel. other genes at play
oh he is blue alright.. he seem to carry a melanizer(maybe Melanotic).. blue is not good at diluting melanotic. not even on wildtype birds.
example Blue Brassy Back
even Splash has some issues diluting Melanotic on some background
Splash Brassy Back
whats the difference between blue and recessive chocolate?..
for one Blue is autosomal(not sex linked), Blue is incompletely dominant and incompletely penetrant(source https://www.backyardchickens.com/t/559750/incomplete-dominant-vs-complete-dominant-vs-incomplete-penetrant) two copies of blue...
My friend Henk didnt add anything new to this topic, we all know Het Dun can be leaky too.
now you are comparing the Pied gene with recessive sex linked chocolate?
