OR maybe just one of the "natural sports" from a
"Blue-Laced Wyandotte" breeding.
( I don't know the GENETICS of it....but it seems to me that they probably DON'T breed entirely "true".)
So...that's what ( I think ) you would sometimes get.
POSSIBLY...Someone on this Forum with education in CHICKEN GENETICS will "chime-in" here.
Possibly a Blue Laced Wyandotte. I just received 10 Blue Laced Red Wyandotte chicks. I do not know if their is a
straight Blue Laced color. But, I do think their are many color variations. Do a Google search for Blue Laced Wyandotte.
One of the first links is all pictures & they are listed as BLRW. You can do this for any breed ! Golden Laced is Gold &
Black ! Hope this helps
BLRW were originally breed by crossing silver laced and gold laced wyandotte so it should be possible to get s gold sport from a pure BLRW mating. You should also remember "blue genetics" you will get get blue black or splash chicks from the cross. So she could really be a BLRW but is showing the black and looks more like a Gold laced wyandotte.
