One or maybe two of my fm girls has some heft to them (relatively speaking, as in compared to the other FM's not like in relation to a cx or anything) Maybe they can add some meat to the bones of the offspring.
Yeah I've had fibro NN way way before GFF got everybody fired up over them.. by 20+ years lol
There is still a mystery to the whole fibro business. There are so many going around saying it is simply being pure for fibro and many also mention being pure for gypsy face too. Easy peasy.... I just have to laugh because my own hands on experience says quite otherwise.
I still don't understand all of it.. and am frustrated sometimes by what to me, seems rather naive beliefs above and lack of anyone else to talk with who seems to really appreciate how weird and hard it is.
So.. it's not a thing like yours being dilute version- I managed to find a study that proved the same fibro gene was the cause behind cemani, silkie, oyge etc. In other words, the cemanis don't have an alternate version of the fibro gene.
My guess is there is something else that either hasn't been found or ??? Unidentified modifer/helper genes... environment? does tropical climate help darken them? Let's move and test this theory out...... lol
A couple things I noticed... the best fibros are on black(feather) chickens- both extended black and birchen based blacks. It's pretty easy to get dark skinned pullets/hens.. the real challenge are fully mature roosters past one year of age with their skin still very dark. Very high percentage show considerable lightening as is, the rate shoots sky high on non-blacks like partridge. I've failed to get a partridge rooster with skin that was any better than medium grayish(kind of soot colored). IMO it;s very ugly and ended up culling the whole lot of partridges out of frustration. I do have a couple pullets and one cockerel that popped up of last year's chicks. Of course the boy's neck is already so light, ugh... he's still around only because he is a potential blue egger(mom lays clear blue eggs).
In any case... save that boy, trust me... he is precious.
