I tried it both ways as well and now I have food outside and water system both in and out, but getting ready to cap off inside one. It drips when they are drinking, (and probably all the time) making a mess in the coop, and I don't want it to get moldy in there. In winter I have a hanging heated bucket with nipples waters outside they didn't have water in coop at all, so I know they will be just fine, My run is covered though,
