Black x Agouti NZ Rabbits stumped on color

[BlueMeadow]

Hello! I’m back again I bred my same agouti to my black doe. On my previous posts, it was the agouti bred to the red, and the black bred to the red brother. Agouti gives reds, black, and chestnut agouti when bred to the red doe, and the black gave steel, harlequin, Himalayan, and black when paired with the red buck and her brother. Okay, now for the conundrum.
I bred my chestnut agouti with my black doe, and got all blacks. Or so I thought. There’s a weird kit that doesn’t look like a chestnut, but more akin to a black otter? I’m not sure if nz can be otter, but the thing is that it also has brown on it. I’ll probably post more pics when it’s older, but for now this is what it looks like

That looks like a chestnut. See the reddish nape triangle, the beginnings of ticking, and the agouti markings:

This kit is old enough to have begun to develop ticking on its forehead, sides and legs, but even as a newborn you could tell it's not a black because of those light inner ears. (The photo of the black, in your second post, shows the dark, solid-color inner ears, rather than the lighter colored ear lining of an agouti or otter). Otter would not have that ticking on the forehead.


Chestnuts can vary pretty dramatically in the amount and intensity of the orange/red tones. But otters will not have any ticking on the head or back: they are more like a self on top, and an agouti on the bottom.

NZs can be any color, although in the US they're only accepted for show in white, red, blue, black, or broken versions of those colors. Even if there's not been a crossbreeding event in many generations, NZs, especially whites, can carry all kinds of hidden surprises, which will materialize if they're bred to a self (black or blue) or an agouti (red).

Okay, I was wondering! Thank you!
