A strange explanation about crossing a Black white-crested Poland Rooster to 2 white black-crested unknown breed hens.

The F1 offspring are Blue (so the hens should be Splash) but they also produced Black offspring !!!


They must be heterozygous blue.

So you say the white black-crested are Bl/Bl (Splashes) along with there other (hidden) color-genes ?

For the interested.

FROM BRIAN READER :
"The black crested whites were made from lakenvelder and other columbian birds over polish. It seems that the Black cresteds then are most likely columbians with eumelanin intensifiers, perhaps charcoal or ebony. They are not clean because there is much heterozygosity and yousee ER, eb, Co, char, S ans s+ at least segregating in these birds. They may have Pg and Ml, owing to their polish heritage, because even if they were made with white polish, the whole group of polish seem to be segregating for most of the traits seen in polish. Dominant white only shows black as spots or ticks and recessive white covers the black altogether in most cases".

Co is incompletely dominant with e+ and eb hens. There is remnant stippling on the back of both hens.
eg:
e+ Co/co+:

Co/co+ expresses more with males.

Then there is Db that gives similar phenotype in hens.
Don't know about Di - might do similar?

Then the quail pattern (eumelanised and with eumelanin restrictor), can produce similar phenotypes (hets. - eg quail cross columbian -tends to be incompletely dominant in adult phenotypes).

Plus, silkie feathers with dark undercolour - tends to show through more to surface.

On the shown photo it's visible the Co/co+ hide the Salmon red chest of the hen but it not causes a wingtriangle !

How the dark (Silkie) undercolor can be changed to light undercolor ?
By adding "Ml" ?

Yes sure wheaten (but I want to stay in Silkies => eb/eb).
Would "Ml" possible cause lighter undercolor on eb/eb ?

The reason I not want to bring in wheaten is I breed only Silver-based Silkies and I fear with bringing in wheaten I would bring in the Salmon-red (autosomale pheomelanin or autosomale red whatever it is called !) so wheaten is not an option for me.
