My Malay boy, Long has double oil glands.
What causes that?

A simple autosomal recessive mutation found in some lines of Asian breeds.

Dpg+ is the Wildtype Dominant Autosomal variant

dpg is the recessive autosomal recessive mutation

I didn't know such a thing existed. Learn something new every day.

It's a Simple Autosomal Recessive trait, it give a beautiful gloss to the egg shell

I don't remember hearing about that one before.

Is the glossiness caused by a change in the bloom or the shell?
Does it have any known effect on how long the egg will keep?
Any known effect on hatchability or on how well the eggs hatch?

I'm wondering whether there is any practical reason to prefer one egg type over another, or if it just comes down to aesthetics.

The change is at the Calcareous Shell,

Any guesses on what genetics are a play with this hen or is she just a poor colored blue laced Barnevelder? (That's what she was bought as)

Thank you.

She has the same Genetic make up as Barnevelder except that instead of eb/eb(e allel mutation responsible for the double laced pattern) she is e+/e+ instead, e+ is the wildtype form that is really not great at producing intricate pattern.

Many hatcheries have e+ running rampant on their stock of Barnevelder, as the result of them using Welsumer to darken their egg shell color because Barnevelder are supposed to be dark eggers, but most now are just brown eggers.

Barnvelder are double laced which their genetic make up is eb/eb, Ml/Ml-Pg/Pg, Poor laced Barnvevelders are e+/e+, Ml/Ml-Pg/Pg instead

Thank you. I have another Barnevelder from the same place and she has great lacing. Luck of the draw, I guess.

I'd imagine just asthmatics. But maybe the glossy ones are stronger (pure speculation)

Does this mean JungleFowl have this trait, or no?
