Yea they will go back inside for food/hay etc.. I too use half hanging baskets.. and have some hay in the run - and also a water bottle... is your run on grass or slabs etc? You could always grow some trays of grass and pop them in the run for amusement/grazing/foraging (to last them all of an hour ) we are doing this.. but I didn't realise how slowly grass grows when you are watching it lol!
