Sorry for this picture but this is the only one I have. (when I submit I lose the picture....sorry) I have 60 day old Black Java's. Most of them have red combs and wattles, but a couple of them have a different color like a cream color. Any one knows what this would mean?
Are you sure it's an actual different color and not just paleness of the comb and wattles?
I have never heard of anyone's Javas having their combs and wattles be truly a cream or white color. Earlobes are a different story. Positive enamel white in the earlobe of Java is a disqualification at a show and these birds should not be bred. If they by some chance do come up with white comb and wattles, then they also would be disqualified and should not be bred.
Paleness could be that they may have worms/illness or they could be late bloomers and just have not caught up to the rest in maturity.
If it is truly a color difference and not simply paleness, I would question the purity of the bloodline and wonder if they had been crossed with another breed.
