This may be a dumb question but we have a metal water fount. We got one of the heater base things that you put the metal fount on. My husband has run the cord into the coop, but could the shavings catch fire? Should we put it outside (seems inefficient)? Or just raise it off the ground more? I'm pretty sure no matter what we do there will be shavings all over. I don't want to burn my coop down, but the nights are returning to freezing this week, so we have to figure out the right placement.
