Normally, a New Zealand should weigh 4 to 4 1/2pounds at about 8 to 9 weeks old. There can be a big variation withthat, though, depending on size of litter, how good a milker the doewas, if the bunny switches to solid food easily, etc.
Hmmm, she might be a mix then b/c I've had herfor almost 7 weeks. Just from seeing bunnies at work, I would haveguessed her to have been atleast 7wks when I got her. There were alotof dwarfs with her. Her fronts legs do seem short to me.
