There is little doubt that Big Medicine developed the Silver Laced variety. I doubt that Dan P reads the posts here any longer, but if so he will get a kick out the one that says he must be near 70 years old. In fact he may not be over 40.
How's the leg color ? I know from my experience of playing around with blue Cornish I can keep a pretty decent yellow on the males, the females not so easy.
Sorry chickenhawk... Gary Imwalle AKA Big Medicine worked on the Silver Laced Brahmas for 20 years and helped Dan with his Silvers. I've been doing some reading on this subject. It's probably better left like that. Check out some of the Brahma Threads. Gary also has some very impressive birds. Like stated above by Sjisty...
