Brahma Cochin?

[Ashleyboz]

I have a hen that was hatched almost all blue and now she’s almost all white with splashes. Never had this happen before! Could someone help me with the reason and what she could be mixed with? Blue Cochin and …..?

I think she's a splash Coaching. Blue doesn't usually breed true, so she's just part of the 25% that will turn out splash. (My hypothesis)

Sorry autocorrect *Cochin

The blue, black, splash gene is an interesting one.There are many neat articles on here about how it works. She seems to be a splash !

I can definitely see the splash now that the blue is white the solid blue on her wings is what had me questioning. Never had anything like her and not disappointed. She’s a sweetheart and nice to look at!

Her now

Is she solid white now?? That could be a genetic mutation. How old is she?

She’s solid white. Not a speck of blue on her. I would say 9ish months!?

That’s so cool. I’m going to tag @MysteryChicken and @NatJ and see what they think about it.

I don't really know.

The mottlng gene does cause a chicken to get more white as they get older, which would perfectly explain why she started almost all blue and ended up white. But the in-between photos do not look quite right, because of the way mottling usually shows on the feathers (white tip first, and I would expect quite a bit of white in the wing primaries). Also, having her completely white at 9 months old is much faster than I would expect if the mottling gene was responsible.

There are several alleles of the mottling gene (several different forms, that are all the "same" in their inheritance and general results, but not identical: slightly different mutations). I suppose there could be one that causes the effect that chicken has, but I really do not know for sure.

Regarding the title, why does it say Brahma Cochin? Based on the pictures I would think she is just a Cochin with no Brahma involved.
