I'm sure this has been asked a million times but I can't figure out what to search for specifically, lol. I bought a waterer with a heated base and plug (with a cord attached). Any tips for plugging it in? It didn't dawn on me until just now (with the temp finally dropping) that I can't plug it in without leaving a gap in the "people" door where I feed the cord out to plug it into the extension cord. This is my first winter with my girls outside. I've been trying to winter-proof things but its been slow going (my own fault since I really didn't start until November was under way, but I'm going to plead Mommy-brain and use my five and one year olds as my excuse, lol; it's been busy around here!) My theory is that I can just plug it in each morning and unplug it at night so that the gap isn't effecting them at night, but is that really okay? I don't want there to be a draft in the coop during the day. Originally, I thought that I was going to have to drill a huge hole into the side of the coop to put the plug through, but when I finally plugged it in by putting it out the back door, I realized that the cord is a lot smaller in diameter than I'd expected -- would cutting a tiny notch out of the corner of the door work? How would I seal around the notch when the waterer was unplugged? I'm trying to read up on every possible tip that I can, so I'd appreciate any ideas you may have!
