OK, few others are real interested in making comments or posting usefull information for these two varieties. I will share some additional information that was provided to me by several different modern game breeders and a Birchen OE master from NM. The use of Brown Red with Birchen is a good idea every few generations. When placing the Birchen male over Brown Red females all the females will be Birchen. They no longer carry the genes that dilute the silver to a creamy or bright white but carry silver in a purer form as the genes they carry to enhance color are for turning gold to red. This results in a clear clean silver in both sexes. This will last for several generations, the same works in the other direction as well to darken the hackle of the Brown red using Birchen females under Brown Red males. cleaner clearer hackle color in females, good crisp color for hackle saddle and wing bow of males.
Never mind. Just mis read it.
I have several Golden Birchen cockrells if anyone out there is working on Birchen or have good Brown reds and would like to work on Birchen. Free for pick-up will only last another week or so around here so let me know if your interested.
