They will LUV the added space. Chickens love to scratch, and flap, and forage, and dig dust-bath holes to China! Chairs, tree stumps, a dog house or couple chairs, treat balls (one owner made a treat bottle out of a small soda bottle), another owner used a child's plastic table, etc, to keep them busy or gives them places to have mid-day snoozes. Noon seems to be the time my girls take their siestas. As for water bowls or plastic mason jar waterers, we discontinued open water dishes because the wild birds(& chickens) would poop or throw debris into the open water so we switched to nipple valve waterers - I'm using the Brite Tap nipple valves with Rubbermaid jugs and the water stays cool and clean for days and days and the mooching wild birds can't get to it!
