I just have 6 girls. I'm thinking I need a waterer both inside the coop and outside in the pen. My question, though is whether I need a feeder both inside & outside as well. It seems like too much to have two feeders, but where should I keep it-- inside the coop our out in the run? They have free access to both during the day & are shut up in the coop at night. The run has wire on the top to keep out wild birds, etc.
