I haven't had much luck with my Californians. They reach 5 lbs at around 16 wks or so. I'm in the process of experimenting. I had 4 Californian does and one Cal buck. I added to that: 1 NZ doe, 1 Harlequin doe and 1 NZ buck. I'm going to experiment and see what I can do with crosses between this and that. What has been your experience with crosses and what has been your best outcome in breeds (for meat)...whether it be purebred or crossed? I'd like to get my rabbits up to 5 lbs at least by 12 wks and maybe sooner.
