In countries (Australia & New Zealand) that have been isolated for over 50 years breeders have become adept at creating or re-creating many breeds and varieties.
Too right. You people down under have done some phenomenal genetic recreations & creations.
I also have a fair number of "black" bantam araucanas -- with various degrees of blackness. I also have several blue and splash birds in the same breed. I'm pretty sure that none of them are extended black, but it makes me think of the whole puzzle surrounding blackness
I find it a bit of a...
Hmmm.What melanizers are we talking about here? It doesn't take Ml or cha, in any case.
You do realise that there are far more melanising genes than have been thoroughly investigated & documented, I presume?
An E bird would be likely to have melanotic (Ml), & recessive black (rb) which, I have...
Now this is interesting, and not something I had considered. Do E (extended black) birds really need additional melanizers in order to appear black? Doesn't the E gene do the trick on its own?
Extended black (E) is not sufficient to make a bird black. Melanisers are needed. A E birds without...
No. It's not from any crossing of varieties, it's just from that black copper line having too many melanizing genes.
While this is true of the French birds it cannot be said to be true of a lot of the Marans in USA. It is precisely one of the problems people are having.
In US all manner of...
I have a couple of hens that were hatched from Black Copper eggs They have Black eyes,and their feet are more black looking than a slate color. Would this come from BC,and Black Marans crossing? Do Black Marans have black eyes,and blackish feet? I've never seen a true Black Marans.
Black eyes...
I think it can be pretty difficult to discern which birds are dark gold birchen(ER) birds & which birds are extended black (E) birds lacking melanisers. Or 'split' (heterozygous) for the two.
The gene which makes the copper black copper as opposed to a simple gold birchen is mahogany (Mh)...
