I have water in the coop and in the pen. Each morning when I let them out of the coop, they run around a bit to get the sillys out of their system, and then they head to the outdoor water can and drink, all five of them. The water (plastic one) can in the coop is seemingly never touched but the food dish is. The water cans are filled the same time so one is not fresher than the other. Also, do you have food both inside and outside the coop? I lock my birds in at night.
