Hi bella, I know very little about chins, but I do know my rabbits love space, the more space u can give ur furies the better, if the room isnt being used for anything much and doesnt have wires would there be any harm letting them have the whole room? My bunnies personalities are so different when they have enough space to exercise and display natural behaviors.
This means you would be able to sit on the floor with them and read a book etc with some treats on your lap they will soon learn to love you!
