NZW's have only one color for eyes... Red, and Red only.
The 'white' coloration is 'masked' over an underlying color.
Crossing any colored NZ buck will 'un-mask' the white allowing
the underlying color to show itself.. """Maybe""" :x :x
You may well end up with blacks, reds, or 'wild-type' colors.
I doubt you'll have brokens, unless your buck has broken in its background.
As to type, they'll still be the same, just colored differently.
You'll also get a portion of whites in the litter.
Years ago, I purchased a 'wild-type' colored New Zealand buck and crossed it
on six of my white does, and got some of the most beautiful reds I'd ever seen.
They turned out to be excellent mothers as well and stayed with me until a man
looking to buy some breeding stock visited and offered a ''huge'' sum of money
for the whole shootin' match..
Three days later, I didn't have a rabbit or cage one... on the place.
Give it a shot.... you'll never know till you try. and Good Luck.
Grumpy.
BTW: I rebuilt my rabbitry and now have over 100 holes that have been
redesigned to slope-fronted cages. They're a lot easier on my arms... (spinal cord injury)
