Not much room in the hutch if sharing with 6 kits. I let the mother out during the day and let her back in at night. Problem was to have her come when I open the cage door. Solved it by leaving the top open. The kits can't get out but she can jump in when she's ready to nurse. . Of course in a couple weeks the kits will be able to jump out too. This will work as long as there are no predators.
