I keep water both inside and outside. Food is kept inside only though. Treats are all fed outside. I'm trying to keep other critters from showing up for a meal. Mine only hang out in the run early in the morning, and then again late afternoon. Most evenings they are in my yard, scratching and pecking away. I've noticed they eat the most of their feed right before going to bed though. Seems they get a morning breakfast in the run, must take a nap during the hottest part of the day, eat again in the run, and when running around the yard. They make sure that crop is filled to the max just right before flying up on the rafters of my coop though! They said my perches weren't high enough, so just ignore them, and fly to the rafters! They are going to get awfully cold this winter....
