[Urgent!]--Chocolate Chestnut or Chestnut?

[viking]

These are pictures from a litter with all Chestnuts/Oranges, and this one oddball.

Father (Black): aaB?CCDDEe
Mother (Fr. Pearl): AAB?cchd_ee

*ANOTHER INTERESTING NOTE*- This (Black) Father was bred with a Sable Point Female, they had all Blacks/Torts, but one baby looked like a Chocolate Self but died at roughly 1 week, I never got a picture of it. Could've been a dirty chocolate but I swear it looked different from the other black self kits.


*back to this litter*
So anyway, this couple (Read above, Frosted Pearl x Black Self) had 7 kits (5 Oranges, 1 Chestnut, 1 Unknown).
The lighter-chestnut baby, in your opinion, would you say is a Chocolate Chestnut Agouti or Normal Chestnut that's lighter for some reason?

Looks very much like my chocolate agouti kits.

Hey thanks for responding quickly and helping

In your opinion how sure would you say you are that it's a chocolate?

That means that both parents were Bb, and most of my rabbits were in some way related to one of those two parents, so most of my rabbits I had were Bb or even bb?

How would I have not had more chocolates then?

Chocolate doesn't affect red pigment so some of your fawns could be chocolate and you wouldn't really tell except for the absence of smut. The easiest way for me to tell a chocolate agouti from a chestnut is in the nest box about week 1. The chocolate agoutis will have noticeably pink skin.

See how pink the nose and foot pads are? As older kits and adults there will be a lack of black pigment. Everywhere there would normally be black, such as the ear tips will be brown. It can be hard to tell the difference at times though.

A chocolate agouti will not have a single black hair on it, and it's eyes will be a softer shade of brown.
Black based chestnut on the left and chocolate on the right.

Thanks so much for helping me with this.
I've concluded that this has to be a Chocolate Chestnut, although it's going to force me to rethink my complete Genetic Rabbit Table.

Although I don't have rabbits right now there are a very good chance I will be getting some in the summertime since we may possess more land.
