Yesterday, we installed (finally!) the PVC feeders. I wanted to be able to fill the feeders from outside the coop, so the 90-degree elbow goes through the coop wall. After jigsawing the hole and installing the feeder, there is a small gap between the wall and the elbow, about a quarter inch. The gap is about 8-12" off the floor of the coop, when measured from the inside of the coop. If it's relevent, the coop is built inside a barn. I've attached pics, inside and out. My questions are: 1. Do I need to seal the gap? Is it a problem for drafts, predators or pests? Or is it okay to leave it open? 2. If I do need to seal the gap, with what should I seal it so the chickens won't eat something they shouldn't? As always...thanks!
