Guest:
You may know I am working on a mottled project with some success (that is if you do not count the horrible losses I\'ve had to racoons). One area they need improvement on is in eye & shank coloration; the mottle gene dilutes dermal melanin. Some black chicks from April  had what appeared to be E down, some ER down. Now comes the interesting part: a few of the ER downed pullets have the most beautiful navy blue shanks, BLUE SOLES, and purple face. Now I have asked a few \"who might know\" to look at the photos and tell me if they might be carrying Fm, and they have guessed \"yes\" and have suggested that Fm is more common throughout many breeds than is commonly thought
Obviously I will be breeding these to a homozygous mottle cockerel to see if this could be a way to help darken the pigmentation. Has anyone else seen this in their flock?

Guest:
including a shot I have of the inhibited dermal (but not epidermal) melanin

and hen with Fm(?)

Hello Rose,

Interesting project.  Where did the mottle genes come from?
I have birchen modern games (E^R).  They are supposed to have mulberry (purple) faces.  I don\'t think this is the same as Fm though.  
I have seen reports of South American Araucana Precursors that have dark skin like silkies.
I have a few lavender pullets that have purplish faces.  I will see if I can get a photo this weekend.

Dark bluish/purple combs appeared a few years ago in my LF and maybe it was the blacks/blues, but don\'t remember for sure.  I didn\'t breed from them, but if the gene is recessive it may still be in my breeders and manifest itself from time to time.  I don\'t think any chicks had it this year, but after hatching almost 1,500 I could be wrong.  
Some of my bantam lavenders, with walnut combs, looked like they had very dark combs.  I think all of the pea combed chicks had nice red combs.
My LF blacks were developed from LF Australop pullets (McMurry chicks) and a medium sized white Ameraucana male (Jerry Segler stock) many years ago.  This same cock was used in making LF whites, buffs and perhaps blues as I recall, using Orpington pullet chicks from McMurry.
Other crosses have been made since with each variety.  In the blacks though I think the only cross was with an exhibition Australop cockerel from Jim Fegan.  I\'ve assumed the blacks were E/E, but have started my LF brown reds a few years back using what appeared to be a fairly nice brown red pullet that just happened from my LF blacks.  I crossed a brown red bantam male from Mike Gilbert over her.  It appears my LF blacks/blues may be E/E and/or E/E^R.  

Jean:
I have had several birds this year with the black face/combs.  They all appear to be pullets.

I am going out on a limb here and going to say it is from my black rooster/hens with the slate legs.  As some of you may remember I am really working on a black flock with slate legs.  

I have had a couple here and there pop up the last two years, but it seems to be more prevelant this year as I have been breeding specifically for that trait.

PS I have no clue what the Fm refers to.  Just thought I would share my experience. :)
