I think mine are lazy- they have at least a couple of hours, sometimes all day, either free or in a pen, yet still spend most of the time in the beds I put out! Although yesterday Roy did go and hide in some tarpaulin and panicked me a bit!
Mine are out whenever we are home. During school time from when my daughter comes home from school about 3.30 till we go to bed sometime between 9-10 oclock. Although the hutch door is open and they have access to the floor the amount of exercise they get is debatable- it depends on what they want to do which in my opinion isnt very much unless food is involved.
