Bantam White crested Polish from White Crested Black, WC Dun, WC Blue parents. Mottle is thought to be carried by at least one of the parents in the flock he is out of. Is this cockerel mottled? The markings don't look like any mottle I'm familiar with.

Here is the progression of his color development.

As a day old (chick on the lower right)


Seven weeks, no white.


eleven weeks, no white


12 or 13 weeks, first sign of white in his hackles


16 weeks


17 weeks (for details of feathers, see original post above)

the only feather color with black at both feather ends and white in the middle part I recall is silver spangled. Maybe this is a very dark, incomplete version of it, since the genes that lead to silver spangled are flowing around in the polish gene pool, as far as I know.

So... you're thinking my cockerel is poorly marked spangle then? I don't understand where it would have come from because the parents have no white on them. Not saying you're wrong, just trying to figure out how. How would that account for his white tipped feathers? Could he be poorly spangled and mottle?

Look up Smyth's DAM line, delayed amelanosis (vitiligo).
Not only is he losing plumage pigment, he has very pale leg colour, unusual for a Polish that should have both dermal and epidermal pigments (id+ ER).
