thoughts on buff and leg color

(1/4) > >>

jerryse:
This will be year 6 of trying to improve leg color on buff bantams.Buff is a complex color in that no one has identified all the genes and modifiers involved.I am beginning to believe that these genes also affect leg color.Crossing in wheaten or other colors gives a dark slate leg but once good buff is achieved they seem to revert to light slate.The polish breed has dark slate on white laced buff.I believe dominate white has turned golden to buff and removed the black lace.Dominate white enhances or darkens slate legs and beak.The sebright breed now has white laced buff with dark slate legs.We may have bumped into a genetic reality in this case.Anyone care to share your results on this subject?

Jean:
A few of my birds carry what I believe is brown and I sometimes get chicks that hatch with dark legs.  I know this is not correct in terms of what we are supposed to base the buff on, but I keep it in my line.

Mike Gilbert:
Jean, what leads you to believe some of your buffs carry brown instead of wheaten at the e locus?   The standard for buffs just says slate, not light slate nor dark slate.   As long as my buffs have some shade of slate, I don\'t worry about the exact shade.    IMHO, there are other important things to breed for that would take precedence, such as egg color and breed type.  

Jean:
I believe this because wheaten based chicks will hatch with pink legs and the ones I am referring to hatch with a dark brownish color that turns slate in a few weeks.  These birds end up having very dark slate legs.

Also some of my chicks hatch with a partridge like pattern, but I don\'t keep those.

And I have some that look like they may be carrying the dun gene.

patridge like markings:


off colored chick, maybe dun:


chick with dark legs:


normal wheaten based chick with light legs:

I realize that without the Pg gene there isn\'t a defined pattern on the chick, but in your case what would be the cause of the coloration that you have shown?  Just curiosity on my part.
