Jean,
When you say you have been \"breeding specifically for that trait\" I assume you mean slate legs, not dark combs?   Have you been breeding from any with the dark combs (I realize they turn redder when they mature)?     If not, then whatever gene is causing the darker heads must be recessive.    If you have been breeding from the dark heads (either male or female but not both) then it is a dominant gene, and therefore easy to eliminate.   If, on the other hand, you have been breeding from both males and females with the darker heads the gene could be either dominant or recessive.   It\'s those pesky unwanted recessive genes that are difficult to eliminate once they get a foothold.

Fm is Fibromelanosis and it colors the connective tissues and causes the dark skin of Silkies, for instance. I guess it can manifest throughout the body and not always the skin and is Dominant Severala people have commented that they did not know a bird was carrying this gene (in some form) until upon butchering they found the dark pigments tissues/bone.
Would any of you have the time to look at the soles and see if your purple/dark faces have dark soles too? Thanks.
I\'m not sure where my mottle gene came from. I had a pair of speckled sussex 12 yrs ago, and the roo was not around for long but he must have sired a black hen.  I started getting white base to feathers, mostly on the tail, on my blue roo after his 2 yr. molt; the pattern of which changed with each molt. Researching what this could be last year, I discovered that a breeder indicated this was an expression of heterozygous mo+. Now there are plenty of people who do not believe this, but it sure has proven to be true for me. I do believe the fact that this recessive gene expresses may have something to do with either the e-loci or the absence of other modifiers... fun stuff.

Mike, I am breeding for the slate legs.  I didn\'t notice if my hens had dark combs/faces.  Of course they look pink to me now.

Barbara, I have blue and black pullets with the dark combs.  The bottoms of the feet are ..... white.  I had to run out and catch a couple of them to make sure.  I don\'t keep any for breeding if their soles are not white.

Since I have noticed that it seems to be on pullets only, could we assume that in my case it may be sex-linked?

FM (Frequency Modulation)is dominate to AM (Amplitude Modulation), but in the old days AM was dominate. ;)

ROFLMAO!!!!!

I guess this late at night some things seem funnier than others.
