I used to breed them about 12 years ago had new Zealands and Californians and some hybrids from a guy up the road, was good fun I sold loads as giant house bunnies ( was the trend at the time ) I could get £4 from butcher or £30 as house rabbits, the bloke still breeds them and would sell you a trio am sure
he sells them to a dealer that I think sends them to France ,
i had a bank of 8 hutches 2ft deep 4ft wide if I was going to do it again I'd use wire bottoms
