Sure hoping someone can help with this- can't seem to find the answers to these questions.
In Black Copper Marans, if you breed a BCM with another BCM split with Wheaten, you will get (I believe it is...) 3 out of 4 chicks that are (pure) BCM, and one that is Wheaten (or, split for Wheaten.).
Does the same testing of extended black and a pure BCM result in having such and such amount of chicks are BCM correct, and such and such amount of chicks also hold true for Extended black? Or, do all chicks automatically become Extended Black? (eb gene too dominate?)
Is there a true, no-fail test for extended black like there is to determine Wheaten in the genes? One more thing- what is duckwing (in regards to BCM)? Is this just regarding the lower wing triangle color? (If it is black, it is crow wing?)
Since eb isn't actually a true black Marans, is there any uses for them other than layers or olive eggers?
Thanks, and very grateful for your time and consideration- these questions have been bothering me for a long while.
