Tim Daniels gives a nice summary on breeding outcomes for chocolates which are gender linked in chickens and ducks.
What genders were the colours for this male's parents?
A Black male is the only bird that may be BLACK but carry chocolate...and therefore produce chocolate offspring when he himself is not a chocolate. in the union.
I find your term:
confusing if this is not the Father.

Your male, to me, does not look particularly chocolate in the respect of what I have seen as chocolate in chickens...they are, well for the most part...just chocolate with maybe a touch of beetle green sheen perhaps.
Maybe someone else may assist and say what your male appears to be.

I just scrolled thru FS and did not see anything that really looks like your male.
I am going to go crack open my Grant
21st Century colour book...he had Clive's choco genetics to play with and maybe I can find a match to yours...
Your bird IS pretty, kinda a sunset burst type colouration on the hackle and saddle...very nice. His tail feathers and hackles, to me in the photo, look more beetle [COLOR=008000]
green[/COLOR] than [COLOR=0000FF]
blue[/COLOR]...but could be the configurations on my monitor or me looking at the top of his hackles...the sides look to be a different colour than black in any shade.
