There is a difference between an Andalusian Blue and a "normal" Blue (but this difference is as good as not to see on the silkie feather structure).
All is in the color-genes.

This is an Andalusian Blue, genetic-code E/E (on S or s+) Bl/bl+ Co/Co Pg/Pg Ml/Ml (these 3 last genes are responsible for the single lacing on each feather-end, this combination is called a crossing-over)

All of your genetic code sequences are very impressive as I have not been able to wrap my head around chicken color genetics. What would you recommend for someone wanting to learn color genetics that has no clue about them? Like a starting point for the basics, links to website, books etc......

I want to have a better idea of what I'm doing with my own breeding programs and know what in the world you guys are talking about when you throw out a code sequence. Thanks in advance for any help.

Here as far as I understand it blue is considered andalusian blue, you can have lacing or not, and then splash. In silkies obviously lacing isn't going to show up because of the feather structure. in the American standard under blue color - it will say under silkies definition of blue something along the lines of "Refer to "Blue" color description" it uses the same definition of blue for silkies as it does all other breeds.

which again because of the silkie's plumage is not going to have the lacing like a straight/hard feathered bird.

FEMALE

Head: Bluish Slate.

Back: Back - an even shade of clear bluish slate, each feather distinctly laced with black.

Tail: Main Tail and Coverts – an even shade of clear bluish slate, each feather distinctly laced with black.

Wings: Fronts and Bows and Coverts – an even shade of clear bluish slate, each feather having a sharply defined lacing of black.

Primaries – an even shade of clear bluish slate.

Secondaries – an even shade of clear bluish slate, each feather distinctly laced with black.

Breast: an even shade of clear bluish slate, each feather distinctly laced with black.

Body and Fluff: Body- an even shade of clear bluish slate, each feather distinctly laced with black.; Fluff – an even shade of clear bluish slate, laced with black.

Legs and Toes: Lower Thighs- an even shade of clear bluish slate, each feather distinctly laced with black.

Undercolor of All Sections: Bluish Slate


Applies to all blue varieties.

NOTE: All Blue varieties are considered parti-colored except self-blue.

NOTE: Blue Fowl, actually of a bluish slate color genetically are black fowl in which the black pigment granules are modified in shape and distribution on the surface of the feather, creating a dilution of black and causing the characteristic bluish slate color. This condition is the hybrid expression of two hereditary color factors, black and a form of white (usually with some splashing), neither of which is dominant over the other, but which are blending in character. Blue to blue will produce offspring one-half blue, the other half evenly divided in black and splashed whites: and blue to black, and blue to splashed will produce the parent types equally, while black to splashed will produce all blues.

That lacing not comes from itself it is caused by the combination of Co/Ml/PG = single lacing
Feathers showing the different lacings => single-, double-, and multiple lacing and what genes (combinations) are responsible for the pattern :

The hen I would honestly consider a pet, she seems to have too long a back, the poor toe feathering, the really light beak...all together I personally would not consider her a breeder. BUT since she is young, she could fill out more in body and could throw some nice offspring, BUT over all I would not sell her labeled as a breeder quality.

The boy is quite nice, and would say he'd qualify as a breeder. He's young so leggy is still pretty normal at 4 months old, he still has plenty of filling in to do but his back looks good for his age, he has a good crest, a good cushion thats starting to fill in, nice foot feathering, good coloring on the comb. His wings are tight but are low/too vertical yes - but not bad over all. I really like your cockerel.

Thank you so much for your honesty. The back is one the the traits that I am really struggling to see well in my silkies. I don't have a trained eye at all. Here is another side shot of the pullet. I just want to make sure it wasn't the photo that made her back look long. It appears she may have lost some hackle feathers as the cockerel is getting "manly".

Look the arrows and compare crest, wing, back, vulture hocks.
