Saladin, I am not sure if you are on the Yahoo Java group of not, but this was posted there:As to the Auburns:
It is just as likely that the Auburns resulted from infusions of RIR or some production breed as to long latent recessive genes. As a matter of fact it is MORE LIKELY that they came from RIRs or Production Reds than those long latent recessive genes!!!
Call them what they are and don't make up some good chicken story. They are a new coloration on an old breed.
Monte has been breeding lots of Javas for years now and never has such a bird appeared.
I bred them a long time too as did Mary Ann and no such thing happened.
MA and I aren't breeding them any longer but Monte still is.
As recent as 3 years ago Monte was having to send Garfield Farm birds because theirs had deteritotated so.

I am also not sure how much you know about genetics, but assuming that the Black Javas are E/E (which would be likely) and that arrangement would never show any other patterns other then mottled.
The historic documents do mention a red colored Java. So that gene was present. It is likely it was eb/eb with other modifiers.
Those colors were lost, and could be very easily. If there were only a few birds with the red color in a flock of blacks, then those resulting chicks would be E/eb and would be pure black and not show other modifiers.
If only a few of those chicks got sold into another flock, then it is possible that you would not see it expressed until that gene was in a closed flock with chicks being bred together. Not only that, but with how genes are passed on, you could need to hatch thousands of chicks before you got a few with that coloration. In addition, an eb/eb bird with no other modifiers would also appear black. You would then need to get a Black Java that is carrying those modifiers into that flock.
And then, you also have a lot of breeders who will cull birds with any odd coloration. Which would make it even harder for those colors to be expressed.
I can understand the skepticism over the Auburns or Silvers and for that reason, I am making sure I do not cross my Blacks with them so I will make sure to never sell a bird with those genes to someone who feels that they are a result of hybrid breeding.
