I prefer frenchies as house rabbits or in sheds. Mine were rescued from the smallest of hutch and they could only lay down with 12" either side. It was horrendous and they were in this for a year. I bought them home here and put them temporarily in my old hutch, which is 5'. It was ridiculous and after 24 hours they got the kitchen.
I know some members do have them in hutches and it depends on how much time they are out of it and whether there is a huge run attached and, my preferences, are not a criticism of others arrangements.
