I like the color of your Orpingtons. I understand that you can come close to this color by breeding a partridge rock with a barred rock, but it doesn't necessarily breed true. It also reminds me of the color of the Bielefelder, that new (in the USA anyway) autosexing breed from Germany. When it comes time to start a new flock, I've thought about Bielefelders. An autosexing breed sounds cool, as does a German breed (I'm Pennsylvania Dutch).
I've heard of the Beilefelders.
The Crele coloring in Orpingtons is actually more complex then breeding Partride Orpington to a Barred Orpington since the first Orpingtons were Buff originally, & most Orpingtons still have wheaten hidden in their genetics.
If they were only Partridge, & Barred based, their genetics will only show this - Male: e^b/e^b, B/B
Females: e^b/e^b, B/-
Since they have hidden Wheaten genes from Buff they also have diluters. This will show as- Males: e^b/e^b, B/B, E^Wh/E^Wh, Mh/Mh, Di/Di, Co/Co, Db/Db
Females- e^b/e^b, B/-, E^Wh/E^Wh, Mh/Mh, Di/Di, Co/Co, Db/Db
Mine are only Wheaten, & Barred Based, but do show hidden partridge genes within their genetics which still make them Crele.
So there's no confusion, I'm talking about Orpingtons.
