Yes, Lilac goes back in her hutch at night. We attempted to keep her in a smaller, secure enclosure but however high we built the fence or blocked the sides, she managed to escape. We should call her Houdini. At one point she managed to jump on the garage roof, I've no idea how. So now we have accepted that she is free-roaming! Our garden is very secure, and there are chickens and rabbits next door who have never been attacked so cross fingers. Not that we have any choice in the matter, Lilac is going to escape whatever we do. I'm just glad she happily goes into her hutch at night.
