I bred a Rex buck ~8.5lbs to a Cali/Altex doe ~10lbs and got ..... Rabbitzilla. They grew extremely fast and the one doe I kept from the pairing dwarfs both parents , she's ~13lbs and has a fantastic blue coat with a real solid build.
Originally I made the pairing with the idea of improving the shoulders of my Rex herd while adding black & blue to the palette.
I have yet to get a litter out of the doe I kept because she didn't take on the first breeding attempt and then I was away from home for 30 days in June & July and will be gone again in the next few days for between 30-90 days. I'm trying to leave as few rabbits for my wife & son to care for as possible ..... they didn't do real well the first time around .... so leaving a pregnant doe is out of the question.
I've been itching to see the results for 6 months now .... have to put it off a little longer.
