I still personally want to see someone prove to me that there are actually crowwing (Birchen) Araucanas out there. Cross a few to a duckwing and tell me, did ALL turn out still looking like Birchen or were there some duckwing-esque birds? Do they all breed true if bred Birchen to Birchen?
I don't mean to offend or anything, I've just never seen a true breeding Birchen Araucana. However I've seen plenty and do have myself some birchen mocking E/e+ Araucanas. (half duckwing half black)
If there are indeed true Birchens out there that's great!
I'd love to be wrong, considering that means there's a whole new world of colors you can use with the Crowwing/Birchen base.
Rumbull -
These are some common and uncommon genes in the Araucanas I've known.
Ml/Ml - Melanizer. This shows up as extra spangling or partially lacing on the bird. In duckwings it shows up on the chest, usually in the same color as the hackle, like here -
Co/Co - Columbian. This is also common in Easter Eggers too; in duckwings it reverses the color of males and in females it darkens the top, increasing the patterning, and lightens and uniforms the bottom. A gold duckwing male with Columbian will instead be black in the hackle/saddle, and yellow and white in the breast and thighs. A BBR with Columbian will instead look much like a Buff Columbian, but red and black. Shown here is a blue-golden duckwing. However with Columbian, the blue is in the saddle and hackle instead of the breast, and the lemon yellow coloration is in the breast and thighs.
Mh/Mh - Mahogany. Basically turns a normal golden/brown bird a nice deep red color, like that of a Speckled Sussex or Rhode Island Red. Shown here is a male with mahogany. His brother is shown in comparison who does not have Mahogany.
B/B - Barring. Although in Araucanas, true crisp barring is uncommon to extinct, the Cuckoo pattern is not. Many, many owners think their Cuckoo patterned birds are something else (mottled, splash, etc) - They're actually a well diluted Cuckoo, hidden amongst many other genes like blue, splash, duckwing, melanizer, etc. As the bird is born, it is born with a faint pale spot on the head, an easy indicator of barring, and as the bird matures, it first looks well barred, then disappears to a weird mish-mash of colors. All dependant on how far from a true Cuckoo the bird has been bred.
Young bird with decent barring:
Semi-adult bird with faint barring.
Adult bird, same one as previous photos, with very poor, practically non-existent barring.
Some other things of note -
This is straight up duckwing. e+/e+
This is straight up solid black (or splash, or blue) E/E
This is half and half. E/e+ - It mocks Crowwing (
E^R/E^R) pretty well, no matter if it is Brown-Red or Birchen or "golden" (
both silver and gold, which is pictured)
You can recognized it the same way as Crowwing (
aka Birchen, Brown-Red, Black Copper) by the bird being black/blue/splash with silver/gold/red in the hackle, saddle, and shoulders of the wing but NOT the secondary feathers in the wing.
Most Araucanas are either E/e+, E/E, or e+/e+
Lavender, Blue, Mottled, Splash, Black, and Cuckoo are all E/E
Duckwing, Quail, Ginger, and Red are all e+/e+ however a true Red needs E^Wh, (Wheaten) and I believe there is such thing in Araucanas but it is rare.
