The Imported English Jubilee Orpington Thread

That is a very fine looking cock bird. Nice and broad with that rich mahogany color.

From what I understand the Speckled Sussex has been used in the Jubilee Orpington in the past and also some American breeders used the SS to create the Jubilee Orp here before it was widely available.

What I've read is that the columbian gene is responsible for the black (or blue, etc) color next to the mottled tip. Without columbian the chicken is just mottled. That's why I suspect your pullets with less black/blue markings are incomplete columbian.

Your suggestion about the E-locus got me curious and I went and did a little research on it. It sounds like the e^b birds show better black banding than the E^WH birds.

With a little luck his offspring shows that same groundcolor and featherpattern.

Not that I haven't seen great looking jubilee Orpingtons here, but the marking on the speckled Sussex looks more neat/refined than on the Orpingtons (and Wyandotte bantams

).
Still putting together how to get that same pattern on the Wyandottes.
Three years ago I noticed that the chicks with stripes in the down became better birds when it came to the markings. The total picture was more black and less white. In my first jubilee Wyandotte bantams (2012), the white and the black was very chaotic.
This was one of the first jubilees here. Her down as a chick was very yellow-ish (wheaten?). I decided not to put her in a breeding pen.


This hen came from the same batch and her down as a chick showed stripes. (e^b?)


Since 2012 I have been selecting very strict on the amount of white and always used a cockerel that showed stripes in his down.
So far, by only using birds from my starting flock + offspring, this was the best pullet I have bred (as for my opinion).


Two years ago I started another line by adding two hens from Holland to the flock. The groundcolor is less mahogany, but the marking is improving.


I believe the columbian gene is responsible for way more than only the black band.

Thank you for answering my question. No wonder they cost so much! That is a lot of trouble for only a few blues. I guess I'll be looking to breed something a little easier...
Creating most any new color will take at least 3 generations. Creating blue jubilees is actually relatively straightforward as far crosses go.

Both of my jubilees had a faint chipmunk stripe. Currently the pullet has more black markings than I would like and the cockerel is not as dark mahogany as I would like.

Right, the columbian gene restricts the expression of black pigment. This is much more apparent on the males than on the females:

Thank you so much for all of the information! Very informative! The chipmunk down trick is pretty cool! I had read about those that did and didn't-but did not know there was a variation in adult coloring based off of it. So cool! Keep all of the info coming!

The down color is actually indicative of what the chicken has for the E-locus (partridge, wheaten, birchen, duckwing, etc.). The Jubilees tend to have either Wheaten (solid color down) or Partridge (chipmunk stripes). From the research I've done it appears that the Partridge-based birds show better black banding on the feathers.

The Columbian gene doesn't show on the chick down. It's only apparent in the adult plumage and works to restrict black pigment.

My new boys. Currently at a friend's place while I make room for them. The little dude is around 2 months and his big brother is about 5. Amazing to see a bird that huge that's still in the "gangly cockerel" phase. He is going to be HUGE when he's done growing.
