We have a small coop with a 8 foot enclosed run. Our chickens also free-range some of the day. To date we've used small (apx. 1 qt) waterer and a pan for feeding. As the girls are getting larger, they really mess up both the waterer and feeder. We move the food/water and the chickens to the coop each night, where we lock them in. We have looked at the stainless pail-type feeders and waterers and they all look so huge for 4 hens. So - two questions: what size/type of feeder/waterer should we use, and where should they be? Do the chickens need water and food in the coop each night? Thanks.
