Several of the chicks from my black/mottled pen hatched as pigeon blue/blue mottled. This is possible as I had blue, blue-chocolate (sometimes called mauve) and mottled and all carried mottled in the pen. Annoying as blue can be as a colour I was quite pleased to have several blue mottled so would be able to select nice ones for the future. However they are all feathering up black. Has anyone else seen this happen? What can the distinctly blue colour of the chicks mean in an ultimately black/black mottled bird?

(Sorry if images too big, how do I get them show smaller.?)

Approximately half of the chicks as hatched,in pics show blue until black comes in. They are blue mottled so blue and white to start but black replaces blue. l . Mainly it shows still in the earlier pictures in the necks which are blue instead of instead of black but rapidly feathering black as in last pic. The difference between blue and black downed mottled chicks is distinct.

Perhaps the cause of the uncertainty is the lack of eumalanising modifiers normally associated with black. It seems likely that good blues do not carry these genes. In my limited experience blues tended to produce a less intense black in offspring that did not inherit the splash gene.
It would be interesting to know what black looks like without any of the usual modifiers.

Hi Marmalade and welcome to BYP.
I can't help with your questions but will be following this with interest as I'm trying to get my head around the whole blue/lav genetics thing. It seems that it is not always straight forward.
I'm envious of of that green grass.

The mottle gene seems to affect the down colour so that black mottled chicks have almost blue down at hatch. The mottle gene in black wyandottes might have an effect on producing more yellow rather than the commonly dusky legs too.
